I keep a blank piece of paper next to me on my desk and whenever I get an idea that doesn’t relate to what I’m working on, I write it down there so I don’t lose focus. I used to keep this as a running list on my laptop’s Notes app, but found that I’d end up forgetting about it or it’d get lost in the mess.
At the end of the day (most of the time 🤭), I go through the notes and either add them to my to-do list for the next day or slot them into my calendar wherever makes sense. It has been helpful in cutting down my constant clicking back and forth between tabs/projects and I find that when I physically write down my to-do’s I remember them better.
