I think the only time I doubted myself was my senior year in high school. I was not offered a Division I scholarship. I remember a scout from Ohio State coming in and looking at my film. He was all excited to meet me. Then he met me and I was 5'10" and he said that I was not a Division I quarterback
It is not always by plugging away at a difficulty and sticking to it that one overcomes it; often it is by working on the one next to it. Some things and some people have to be approached obliquely, at an angle.
I might not understand everything a Democrat or liberal thinks but hey let's be honest, I don't understand some of the things the Republicans think, but that doesn't make me some dumb hick that doesn't have the right to live here.
