On the one hand, I don't like notebooks, because they make it hard to reorganize notes and I prefer electronic notes, because they take less space. However, I use notebooks when I have to think and they help me concentrate. So while I prefer to organize things electronically, I feel that the thinking process actually works better for me, with pen and paper in front of me.
Usually, I make some notes while thinking things through and return to the PC to implement them afterward (Code as well as PowerPoint).
So I can't emphasize this enough:
> They aren’t a record of my thinking process. They are my thinking process.
