Clairefontaine engineering ruled spiral notebook. There are various sizes but I prefer the larger one. Good paper feel, inks don’t bleed and it survives riding about in a backpack with the laptop. Everything goes into it so there’s only one item to remember. Pages are dated, key entries are highlighted. Bits can be scanned. If I know when something happened, I can scan backwards to restore state. Even random scribbles go in, and the gridded pages help drawings. “If you don’t write it down, then it never happened…”. Yeah, some do it with a keyboard, but I find it hard to draw, scribble or whatever when I have to switch devices or associate drawings with text. Eventually, they’ll figure out a tech solution to all this but notebooks cost like $10-20, survive impact and even survive a bit of liquid. No, I didn’t think this up myself. Merely watched a boss never lack info on what went down last meeting or last week.
