To blog or not to blog

A girlfriend suggested I should try blogging. She says things are too funny and too serious in my life all at the same time. Truth is my life is a bit like a great drama/comedy. It's not real exciting so not a lot of suspense or adventure here. But if you need to find the funny in the mundane...then I'm sure I've got it.
My first fear about blogging is that I'm going to be judged for all that I say. And I'll admit up front that I really like it when people like me, so I may cry a little if someone disagrees too strongly. And if I end up requiring years of therapy to bounce back from a mean heartless response, then I might send a bill! Be warned!
Then I'm also afraid that I might incriminate myself. A good blog is an honest one, right? But I suppose that if I say I'm really trying to stick to my diet but then admit here that I did eat that whole bag of cookies, well...it's incriminating.
Oh - and I'm afraid that I might discover that I am a complex person full of twisted philosophies that often work in opposition to one another. You know when you THINK you know it all and then BAM! You find out that you are the biggest hypocrit around! Ok...so if that's me, I'll apologize in advance.
Otherwise, I think this might be fun. We'll see!
