I still believe I am completely incapable of doing things I know (and have proven) I am totally capable of doing.
Best examples: Every Sunday is a spin endurance class. The first three Sundays of the month are 90 minutes, the last Sunday of the month is 2 hours. Yes, spin. The very class I told myself I was too fat to try. (And by the standards I was using, I still am. And that was a year ago.) So I've been doing this endurance class most of the last year. And yet, every week I am sure I am not capable of of this class. I somehow manage to push that to the back of my head and just tell myself to try. If I can't finish the class, I can't. But I do. And yet the next week we go through the same thing.
I'm not really sure what's really going on in my head that brings this on every week. I know people look at me and would never assume I take spin, let alone an endurance class. But why do I think that about myself?
