Doubts

I've posted a couple entries now and have this nagging thought: am I doing it right? Basically, when I was thinking of writing a blog I thought I needed to vent my frustration and anger and everything else. But when I actually started writing I found myself sort of editing what I wrote, trying to make it nice for somebody reading it. Explaining myself, not expressing myself.
It's a bit sad that in this anonymous blogging world I still can't just say what I think and feel openly, I keep censoring myself, adding those rational comments I don't even believe in, but it's what you say...
