The most important trick? Write it down right now. Not two hours later, not tomorrow morning. That’s like trying to remember a dream after breakfast – the details are gone.
If you finish a task, pause for five seconds. Scribble the end time. It feels silly at first, like taking a photo of your lunch. But future-you will be so grateful.
Imagine future-you as a detective. They’re looking at the timesheet and saying, “Aha! So that’s why I was tired on Wednesday!” It’s genuinely satisfying.
