Writing and literary magazines

I write, a little bit of everything: poetry, a novel (in progress), short shorts, a blog (obviously), lists of all kinds, notes to myself, a lot of things I never finish, and I journal, but I think that was all fairly common knowledge. The problem is, I don't know what to do with anything after it's done. There are like a million literary magazines and I have no idea which ones are right for me. Online or print? Artsy or edu-ish? The problem is: I know what I like to read, and I like to read what I write, but is what I write like what I like to read? Sometime consider the fact that a lot of popular authors are published and become famous posthumously, that could be me, but then I shouldn't hold back so much when I write. Get it all out there, ya know? But I really want people to know me when I'm alive, like my writing, want to read it, can't wait for more. That brings me back to the problem I started with: where to submit?
