I keep a big notebook (12" x 9" I think) that I write quotations I like in, with a fountain pen. I try to transcribe one quotation per day, from a computer file of such quotations. This keeps my hand in with respect to handwriting, keeps my fountain pen from drying up, and doesn't take too much time.

I also keep a journal, but I do that on computer because I value being able to electronically search it.
