What Drives Your Note Book?

The note book is the centre of my day. There's always certain things that i have to do m when i manage one of my clients, emales. I don't need to write it in my planner, because it's something that's constantly present. But if there's a project for that client or very specific, like, some sort of research thing that i need to do for them, i'll put that in my notebook. Or if there's something that i know that i haven't gotten to in the past, i will put that in the planner. So even though my planner is kind of that centred peace moment, i don't actually end at putting everything specifically in there
