Yes, I keep a couple different types.
I've got 4 or 5 books filled with poetry that's I've written, although a couple pages are poems I've found online that I liked-
And I've got a hardcover book filled with blank pages- that I draw in, kinda like my drawing portfolio- otherwise my non-hardcover sketch books are basically doodles that just look good but don't ever get finished
And I've got 3 or 4 journals that I write in- started back in middle school; I don't write in them everyday, one I lost- found again- lost again, found again, etc- and when I find it I 'caught up' so to speak, there'll be a few times where an entry is more than 5 pages long for a short non-detailed what went on, did I ever finish a goal, etc-
And I've got one special one put aside that I started back in Nov- and it's basically just my life /daily thoughts- to my ex- I plan to continue writing in it until he gets home. (he's deployed) Back when we were dating and I was keeping it, I'd write in it almost every night - just with the simple words saying "thinking of you- <3, amanda' and the date- but now it's basically just my blogs printed off and taped into it. Not the same- but I wanted to do it because he was so scared that he'd miss something. there's also some pics and such in there. He doesn't know about it- but when he gets home I'll give it too him.
And my journal consists of dreams, goals, fears, vents, happy thoughts, quotes, a really special poem I might have written/found, pictures, or even just random thoughts. I don't write in it everyday- nor do I try to. When I think about it- I write in it- or if something happened that I want to remember, like a night out or whatever- I do so also.
