Journals

As a kid, I would always start a journal. I would write in it for a couple days, two weeks at best, and then I would forget about it. It'd be too hard to keep up, to think of ideas, to remember everything that happened.
And I sort of feel like this blog could morph into that.
But I'd like to start carrying a journal again, but I feel like I wouldn't know what to put into it.
Jokes?
Names?
Phrases?
Moments?
Ideas like names for my friend's pet turtle?
I really don't know.
If you have a journal, what do you use it for?
And do you recommend a certain size or brand for easiness?
I think I might just pick up a Moleskine.
