A lot of people don’t just go ahead and try things. They’ll have an idea and they’ll say — they’ll convince themselves or other people will convince them that it can’t be done. You know, one or the other. Actually I think that the first is even more dangerous and more serious. It’s convincing yourself that it can’t be done.
