If you’ve been searching for how to build confidence as a leader, stop second-guessing yourself, or make better decisions under pressure, the answer might be simpler than you think.
Sleep.
Rest and self-care are the foundation your leadership and decision-making sit on top of, and most of us treat them as the very last thing on the list.
Meet Amelia
I want to tell you about a woman I worked with. Let’s call her Amelia.
Amelia second-guessed everything. Every decision came with a layer of “but what if I’m wrong”, and she’d check, and re-check, and ask for permission before she moved. It was frustrating her boss, and honestly, it was frustrating her too. She knew she was capable. She just couldn’t seem to back herself.
We dug into it. And the thing that shifted everything wasn’t a confidence framework or a mindset hack.
It was sleep.
The shift that changed everything
Amelia started prioritising her rest and her self-care properly, for the first time in a long while. As she did, something changed. She stopped asking permission. She started making decisions and standing behind them. She moved from the passenger seat into the driver’s seat of her own work.
Her relationship with her boss improved too. He’d been tired of the second-guessing, and he’d tried to give her feedback to that effect. Once she was rested, she stopped waiting for permission and started leading. She was genuinely stunned that sleep played such a big role in her self-belief.
What happens to a depleted leader
I’ve seen this pattern more times than I can count. When you’re well rested, your judgement is sharper, your patience holds, and that little voice telling you “you’re not good enough” goes quiet.
When you’re depleted, the opposite happens. Your decision-making wobbles. Your patience thins out. The voice gets louder, and you start reaching for reassurance instead of trusting your own call. You end up managing your energy crisis on top of everything else you’re carrying, and the leadership suffers for it.
We talk about leadership like it’s all strategy and presence and tough conversations. Those matter. But you cannot lead well when you’re running on empty. All the frameworks in the world won’t fix a decision made by an exhausted brain.
Self-care is the real work
Self-care is the real work. It’s what your decision-making sits on top of. Get the rest right, and everything you build above it becomes steadier.
I see this constantly as a coach. Sleep is the first thing that gets kicked to the kerb when life gets busy, and life is always busy. I hear people bragging to each other about how little sleep they need, and I wonder how it’s shaping their decisions and their confidence over the long term. I’d love to change that conversation. Let’s get addicted to more sleep, more clarity, more confidence.
How to start backing yourself
You don’t need a grand overhaul. A few practical shifts go a long way:
- Treat sleep as a non-negotiable, not a reward for finishing everything else. It never all gets finished.
- Put your rest in the diary. If it’s not in the diary, it doesn’t happen.
- Notice when you’re seeking permission or reassurance. That’s often a signal you’re depleted, not incapable.
- Before a big decision, ask whether you’re rested enough to make it well, or whether it can wait until you are.
The question worth asking
So before you set big goals for the new financial year, ask yourself the unglamorous question.
Are you rested enough to lead the way you want to?
