To track your energy, log a number from 1 to 10 once a day at the same time, tag what you were doing, and write one line about what charged you and what drained you. Then read the log back after a few weeks. The pattern shows up in what repeats, not in any single day. One check-in a day teaches you more than three you keep meaning to do.
Why track your energy at all?
You already know when you’re wiped out. You don’t need an app to tell you Thursday was rough. The part you can’t hold in your head is the pattern underneath it, because a flat Tuesday and a flat Saturday feel identical while you’re in them and they usually come from different places.
I started logging mine for a plainer reason than that. I love having data on myself. The more information I have about everything, including me as a person, the better. So I built a tracker in April and I’ve been checking in almost every morning since.
What I got back wasn’t what I expected, which is the whole argument for doing it.
What should you log each day?
Five things, and it takes about 15 seconds:
- A number from 1 to 10. Your energy right now, not your energy in general.
- The time of day. Morning, afternoon, or evening. This is what lets you compare like with like later.
- Tags for what’s been going on. Exercise, sleep, food, work, social, outdoors, creative, rest, caffeine, alcohol, screen time, meditation. Twelve is plenty. A longer list makes you think, and thinking is what stops you logging.
- What charged you. One line. “Slept eight hours.” “Walked at lunch.”
- What drained you. Also one line. “Four calls back to back.”
The number on its own tells you almost nothing. The number sitting next to what you were doing is where the information is.
What did tracking my own energy show me?
Talking to a person lifts me. Almost any person.
I work from home by myself, so I can go a long stretch without speaking to anyone who isn’t in my house. I’m an introvert, so this surprised me. My own log says something more specific. A call with a friend, going to Pilates, running out to the store, even a pleasant exchange with a receptionist, and my number goes up. Not by much, but it goes up.
I genuinely didn’t know that until I started writing it down.
The other half of it showed up in the same log. Too many days in a row of plans or outings and I’m flat. A little contact charges me and a full week of it empties me, and the only reason I know where my line sits is that I wrote down enough ordinary days to see it.
That’s the kind of thing tracking gives you. It corrected something I’d assumed about myself.
How often should you log your energy?
Once a day, welded to something you already do without thinking.
I check in every morning as part of my morning routine, and I almost never miss, because once something is in that routine it happens. I don’t think I’m especially disciplined about it. I attached it to something I was already doing every day.
I’ll also be honest about the ceiling on that. Logging once a day only shows me my mornings. Two or three check-ins would tell me where my afternoons go, and I’d learn more from it. I keep meaning to. So take the once-a-day version as the floor worth hitting, not the ideal, and if you want the fuller picture, add an evening one and anchor it to something equally automatic like putting your phone on the charger.
The same logic runs underneath staying consistent when you’re tired. Shrink the thing until your worst day can still do it, then let the streak survive on structure instead of willpower.
How does this fit with raising your vibration?
The woo answer and the practical answer agree here, which doesn’t happen as often as I’d like.
Advice about high-vibration habits and low-vibration habits is sound, and it’s written for everyone at once. Sunlight, movement, gratitude, less doomscrolling. All true. None of it tells you which one moves the needle for you, or how much of a good thing tips into too much.
Your log does. Mine says human contact raises me and stacked plans flatten me, and no general list was ever going to hand me that.
How do you read your log once you have one?
You don’t need to analyze anything. Open the last few weeks and look for what repeats, the same word turning up next to your high numbers, or a day of the week that keeps sagging. Three or four weeks is usually enough for something to surface.
Then use it on purpose. When I’m down now, I open the log and find something on my own charged-by list, and often it’s as small as calling someone or getting out of the house. Those are on the list because they already worked for me, so I’m not guessing.
Today’s action
Pick your anchor and log once. That’s the whole task.
- Choose something you already do every single day without deciding to. Coffee, teeth, phone on the charger.
- Right after it, write down a number from 1 to 10, plus one line for what charged you and one for what drained you.
- Put it wherever you’ll see it again. A notes app, the back page of a notebook, a tracker.
- Do that for three weeks before you try to read anything into it.
Where should you keep an energy log?
Anywhere you’ll open again. A paper notebook works. Your notes app works.
If you want it structured, I built Energy Battery for exactly this. Logging is free and unlimited, with the 1 to 10 slider, the twelve tags, and the charged-by and drained-by lines. Free accounts see the last 7 days of history, which is enough to start reading patterns by eye the way I do. The Pattern Insights tab, the one that works out your averages by time of day and day of week and tells you which tags run above your baseline, is a Pro feature at $7 a month, and that one subscription covers all five Jen Built It apps.
Everything I’ve described in this post you can do free, in the app or on paper. I’d rather say that plainly than let you sign up expecting the charts.
Frequently asked questions
How long does it take before energy tracking tells you anything?
About three to four weeks. A single week gives you noise, since one bad night’s sleep or one busy weekend colors everything. By the third week the same words start repeating next to your high and low numbers, and repetition is the signal.
What if I keep forgetting to log?
Attach it to a habit you already have rather than trying to remember it on its own. I don’t miss my morning check-in because it sits inside a routine that runs whether I’m motivated or not. If you’re missing days, the problem is usually the anchor, not you.
Is tracking my energy going to make me obsess over it?
It doesn’t have to. Keep it to one number and two short lines, and cap it at once or twice a day. The point is noticing what repeats over weeks, so checking in constantly adds anxiety without adding information.
Can I track my energy without an app?
Yes. A notebook and a pen do the job, and so does a running note on your phone. Write the date, a number from 1 to 10, and your two lines. An app sorts and averages it for you, and none of that is required to spot a pattern you can already see by reading.
What do I do once I know my pattern?
Use it in both directions. Put more of what charges you into the weeks you know will be hard, and watch the thing that drains you before it stacks up. For me that means finding some human contact when I’ve been heads-down for days, and watching for the stretch where plans start stacking up on each other.
Does energy tracking work if my schedule is different every day?
It works better, actually. An irregular schedule is exactly the situation where you can’t hold the pattern in your head, so the log is doing more for you than it would for someone with identical weekdays. Lean on the tags, since they’ll carry the signal your calendar can’t. To track your energy, you need one number, two lines, a fixed anchor in your day, and three weeks of patience. Everything else is optional. Plant the first check-in tomorrow morning and let the pattern find you.
