Time management assumes you're a machine. Energy auditing recognizes you're human.

For over a century, we've been operating under an outdated work paradigm installed during the Industrial Revolution. Back then, factories needed humans to behave like perfect robots because robots didn't exist yet. Workers on assembly lines had to maintain consistent output hour after hour, regardless of their natural rhythms, energy levels, or capacity. The system worked because the work itself was mechanical.

Fast forward and now we actually have robots. We have artificial intelligence. The mechanical work that once required human consistency can be automated. Which means: the best way to work alongside these technologies is to double down on what makes us uniquely human.

The human traits most valuable in the modern economy are the same ones valuable inside vibrant families and communities: pattern recognition, inventive solutions that help people, and the ability to build strong relationships. These capacities don't operate on factory time. They require something time management can't account for: energy.

The Industrial Revolution Hangover

Your calendar tells you that Tuesday at 2 pm is free every week, and therefore is perfect for Deep Work. That each hour offers equal capacity. That if you just organize your time better, you'll get more done.

Your body knows this is nonsense.

You've likely already felt it. Some mornings you wake up sharp, ideas flowing, decisions coming easily. Other days, even simple tasks feel like moving through mud. Some weeks you can handle complex strategic work. Other weeks, checking boxes feels like all you can manage.

Time management treats all hours as interchangeable units. Energy auditing acknowledges what you already know: you are not a robot. Your capacity varies. Your energy shifts. Your nervous system needs different things at different times.

After 20 years working with visionary entrepreneurs, here's what I've observed: the people who try to force themselves into rigid time management systems eventually burn out or rebel. The people who learn to work with their natural energy rhythms build sustainable practices that compound over time.

What Energy Auditing Actually Means

Energy auditing is simpler than it sounds. You don't need sophisticated systems or technology. A piece of paper works.

Start by tracking your energy for one week. Specifically: when do you feel energized? When do you feel depleted? What types of work feel easiest at different times of day?

You're looking for patterns in several types of energy:

Creative energy: When ideas flow. When you see connections others miss. When solutions emerge without forcing. For many people, this happens early in the day before decision fatigue sets in. For others, their best thinking comes late at night or very early in the morning before anyone else wakes up.

Strategic energy: When you can see the whole system. When you can hold multiple variables and find the optimal path. When planning feels clarifying rather than overwhelming. This requires different neural resources than creative work.

Administrative energy: When checking boxes feels satisfying rather than soul-crushing. When organizing, responding, and completing tasks flows naturally. Some people have this energy in short bursts between bigger projects. Others prefer batching it into dedicated time.

Relational energy: When connecting with others energizes rather than depletes you. When you can hold space for someone else's needs without losing yourself. When collaboration feels generative rather than draining.

Everyone fires on a different schedule. The work is figuring out when each type of energy is naturally available to you, then designing your work rhythm to match.

The OODA Loop: Observe, Orient, Decide, Act

This framework from military strategy applies perfectly to redesigning your work rhythm:

Observe: Track your natural patterns over the course of a day or a week. No judgment, no fixing yet. Just notice when you feel sharp versus foggy, creative versus administrative. What time of day? What day of week? After which activities?

Orient: Look at your current calendar. Which parts honor your natural rhythm? Which parts work against it? Where are you forcing yourself to do creative work when you only have administrative energy? Where are you wasting prime strategic time on inbox management?

Decide: Which changes can you actually make? This might mean rescheduling certain types of meetings. Using time blocking as a personal modality to protect your best hours. Adjusting your calendar availability on schedulers. Moving calls that drain you to times when you have more capacity.

Act: Make the changes. Move those calls. Adjust your public calendar availability. Communicate boundaries. The resistance you'll feel here is often about guilt or fear of disappointing others. You're not serving anyone well when you're running on empty.

The 20-Minute Strategy

Here's what works: focused bursts over marathon sessions.

The Pomodoro Technique exists for good reason. Twenty minutes is plenty of time to get a solid start on something, then take a break and come back to it. You can accomplish more in short focused bursts than in long depleted stretches.

If you fall into flow and hours go by on an activity you love, perfect. That's the ideal state. But most people miss one thing: flow requires slack in the system. When you're constantly overbooked, constantly pushing through depletion, flow becomes impossible. You're operating in survival mode, not creative mode.

Leave enough space in your schedule that flow can happen. This feels counterintuitive because time management logic says "fill every hour." Energy auditing says "protect the conditions that allow your best work to emerge."

Many of our workdays contain activities that don't require flow or won't bring us into it. That's fine. Match those activities to your administrative energy windows. Save your flow-capable time for work that actually benefits from it.

The Three-and-a-Half-Day Workweek

Story time. In November 2022, ChatGPT launched. I knew this mattered. I'd spent 8.5 years with Peter Diamandis learning to recognize interface moments in exponentially developing technologies. I took the next month to offboard all my clients. Then I spent three months going full "AI-first," figuring out how to adapt my workflows and behaviors to leverage technology rather than compete with it.

Three months of unlearning and relearning.

Then on March 16, 2023 (my birthday), I asked myself: what would my ideal rhythm for the next year actually feel like?

I reflected on my favorite periods of time. They were the spaces between clients when I wasn't locked into a five-day workweek. I realized what I really prefer is a four-day weekend. Enough time for laundry and logistics, rest and recuperation, a little adventure, or even a short trip. The perfect amount to fully recharge.

With a four-day weekend, when Tuesday came and it was time to work again, I could absolutely hit it hard. All that energy I'd built up from resting meant I could go deep and focused. The work that emerged during those three-and-a-half days was higher quality than anything I'd produced working five or six days straight.

As AI and large language models got more advanced, I had three-and-a-half days for revenue generation plus one-and-a-half to two days a week freed up for evolving my own skills and capabilities. Time for thinking, learning, connecting. The rhythm worked because it honored how my energy actually operates, not how a factory clock said it should.

I've maintained this rhythm ever since. Ultimately, it's because I refused to build a life that requires my depletion to function.

When Time Management Failed Me

I've tried forcing myself into other people's systems more times than I want to count.

The pattern was always the same: a client working 5 am to 7 pm, and I'd want to be responsive during those hours to keep the contract. I'd find myself matching and modeling their rhythm because it felt like good service. Then I'd burn out. Hard.

Every time I'd reflect back and realize: I burned out because I forgot my own rules. I laid myself inside someone else's system instead of following my own.

Here's what that looked like practically: morning calls before I was actually awake. Back-to-back meetings through my best creative hours. Administrative work squeezed into late evenings when I needed to be resting or wanted to be with my husband. A calendar that looked productive on paper but left me depleted and resentful.

Sound familiar?

The turning point was recognizing that working inside someone else's paradigm (even a client's) meant abandoning my own capacity limits. I wasn't serving anyone well when I was running on fumes.

Start This Week

You don't need to redesign your entire calendar right now. Start with observation.

For the next seven days, track three things on paper:

  1. Energy level throughout the day - You don't need a 1-10 scale. Just notice: when do you feel sharp? When do you feel foggy? When energized? When depleted?
  2. Type of work you're doing - Is it creative, strategic, administrative, or relational? Does the work match your available energy or work against it?
  3. What happens after - Which activities leave you energized? Which leave you drained? What do you notice about recovery time?

After one week, you'll see patterns. You'll know when your creative energy is naturally highest. You'll recognize which types of work deplete you fastest. You'll understand your recovery rhythms.

Then ask yourself three questions:

  1. What in my current schedule forces me to work against my natural rhythm? (Morning calls when you're not awake? Creative work in the afternoon when you only have administrative energy? Back-to-back meetings with no recovery time?)
  2. What's one change I can make this week? (Move one recurring meeting? Block one morning for deep work? Batch administrative tasks to match energy windows?)
  3. Whose rules am I following? (Your own? A former boss's? An outdated paradigm about what "professional" looks like? A client's rhythm that doesn't match yours?)

Start small. One change. See what happens. Let the evidence guide you rather than forcing yourself into someone else's system.

Service That Strengthens

True service strengthens both the giver and the receiver. Service based on self-erasure eventually collapses.

If you've been taught that good work requires pushing through exhaustion, that professionalism means availability at all hours, that dedication looks like depleting yourself, consider this: service that drains the giver corrupts the gift.

You can't give from an empty cup. That's not a self-help cliché. It's physics. Your nervous system needs recovery. Your creative capacity needs space. Your strategic thinking needs rest. These aren't luxuries. They're requirements for sustained excellence.

Energy auditing isn't about being less productive. It's about being productive in a way that's actually sustainable. About matching work to capacity instead of forcing capacity to match arbitrary schedules. About recognizing that the human traits now most valuable in the economy - pattern recognition, creative problem-solving, relationship building - require you to work with your nature, not override it.

Your calendar is lying to you. Your energy is telling the truth. Which one will you trust?
