I handwrite my todo list at the start of everyday and scribble notes down when I’m in meetings and almost never look at them again. It definitely helps solidify things in my head for whatever reason. I’m not uptight or anything, it just seems to help me.
This is me. I've tried various note taking apps but I never stick with them for more than a few days.
My notebook is everything. If I don't have it for any reason (most often: it ran out and need to buy a new one) my productivity actually takes a big hit. Basically: if I don't write it down, I probably won't get it done.
