Starting to blog

Blogging is about sharing the things you get up to? I don't think I have enough to talk about, but my current obsession is dieting and exercise. I've been part of a well know weight loss company for the last 5 years. I've tried Online, At Home and At Work! I have now gone back to the get weighed each week system. It works for me as I get the fear every week. Crazy as I'm paying for the privilege. I mean I could stop whenever I want, but I can't.
