I'm looking for notebooks that I can have with me pretty much always. I've had a few TBIs and my memory is all kinds of messed up.
I'm looking for notebooks that I can use to easily catalog notes, and solutions to problems and such. I need them to be tough because I do a lot of outdoor stuff for fun and for work. I work on cars for fun, I go hiking, and kayaking, and I work with petroleum and the environment and so on.
I guess I need them to be a decent size but not too big, because I think I'll have to carry a few to separate work from hobbies, from day to day stuff.
On your note about carrying a few notebooks:
I was in this same boat. I carried a paper planner, a notebook for notes and lists, and another one with graph paper for projects (wiring diagrams, building floor plans, etc). I've been using a Midori travelers notebook for the last year. It's essentially just a nice piece of leather that holds inserts (think field notes type notebooks). I have 3 inserts in mine that cover those areas and when they fill up I can replace each one individually. I'm loving it and the leather looks really classy.
