How to: Daily Journal

Originally published on LinkedIn.

I used to end my workdays wondering where the time went to. Meetings, code reviews, random questions, context switching.

Before I know it, the day feels busy but directionless.

That’s why, for the past two years, I’ve been keeping a simple daily bullet journal. Nothing fancy.

Each day, I simply write down a small set of work tasks: a couple of must-dos, a few optional ones, and short notes when I learn something or notice a pattern.

It helps me be intentional about where my time and energy go, and it gives me a clear handoff to my tomorrow self so I don’t have to reload context every morning.

I’m still refining how I do it, but this small 5-10 minute habit alone has made my days feel more planned and more deliberate. If your days feel cluttered or reactive, this might be a good time to add a small new habit into 2026 :D
