You just called out the single most important hindrance to productivity: being afraid to note something down. I too went through several Moleskines a few years ago because I didn't want to ruin them with crap pages. It sucked - whenever I did a page that looked "bad", I just moved to a new moleskine. Sadly, notes are not supposed to be neat, much like your brain isn't. My biggest productivity improvement in recent years (apart from disabling any new email notifications) was the day I stopped being "afraid" to take notes on my notebooks. In the end, they always look awesome and valuable, regardless of how careful I was about making them look neat.
