Willpower and judgement: Protect your decision-making energy
Master your decisions. Master your day.
By Joni Peddie, CEO of Resilient People
HERE’S a confession: by 4pm most days, I have made a thousand decisions, and I have zero left in the tank.
What’s for dinner? Ask me at 9am and I’ll wax lyrical about a balanced meal. Ask me at 4pm and the answer is “fruit and yoghurt, standing up at the kitchen counter”.
That’s not laziness. That’s decision fatigue. And if you’re leading a team, a business, or a family, you will relate.
I see it constantly in the leaders I work with: the CEO who is razor-sharp at 8am but can’t decide between two almost-identical vendor proposals by 3pm; the manager who handles a crisis brilliantly, then goes home and vegetates in front of the television, unable to chat to their significant others.
Here’s the thing nobody tells you about leadership: it’s not the big decisions alone, it’s the sheer volume of them. Every email reply, every ‘quick five minutes’, every ‘need your sign-off’ chips away at the same finite resource. Willpower and judgement share the same tank.
The result?
- Snap decisions (without thinking through the consequences) dressed up as decisiveness.
- Lots of small, irritating errors late in the day.
- Snappy retorts and bad tone as you get tired in the day.
- A creeping reliance on ‘I’ll decide tomorrow’.
So, what do we do about it? Here are five ways to protect your decision-making energy, rather than spending it until it’s gone.
1. Rank your decisions, don’t simply react to them
Not every decision deserves the same weight. Some need your full brain, others only need ‘good enough’. Before you dive in, ask: does this deserve five minutes of best thinking, or thirty seconds of good-enough thinking? Most of us default to the former, even though most decisions don’t require it.
2. Front-load the big calls
Your judgement is sharpest early in the day, before small decisions wear it down. Put important calls in the morning, save routine stuff for the afternoon slump. I schedule anything requiring real judgement before midday. After that, it’s ‘transactional tasks’ only.
3. Build ‘decision-free’ defaults
Every recurring decision you automate is energy saved for later. Before bed: lay out your exercise gear, tomorrow’s clothes, and your lunch. Small tasks, but they eat into the next day’s energy bucket. Skip the lunch prep and you’re tired by 3pm, grabbing a coffee and a chocolate bar instead, because the bucket is empty. Grab with two hands what you can control: ‘no morning meetings’, a default ‘no’ to anything landing with less than 48 hours’ notice. Hmmm … I often break that last one, and my ‘irritation barometer’ sky-rockets every time I get a last-minute request.
4. Set a decision budget, not merely a time deadline
We give ourselves a deadline, ‘decide by Friday’, but rarely acknowledge a limited number of good decisions per day. Make forty before lunch, and decision forty-one won’t get your best thinking. Notice when you’re running low, and push important stuff to tomorrow morning rather than forcing it through on empty.
5. Protect recovery, not only time
Rest restores decision-making capacity the same way it restores physical energy. A short walk, a proper lunch break, five minutes of doing nothing. These aren’t indulgences, they’re refuelling. Leaders who treat recovery as optional are choosing to make their afternoon decisions worse.
The goal isn’t fewer decisions. Leadership doesn’t allow that luxury. It’s spending your decision-making energy on purpose, instead of leaking it out through small choices before the big ones arrive.
Remember: judgement and willpower are resources, like time or energy. The leaders who protect this bucket are still making sound, confident calls at 4pm. Let it run empty, and you may end up doom-scrolling on your phone for an hour … telling yourself it’s “just five minutes”.
Master your decisions. Master your day.
