unrealistic?

I think that there’s a certain delusional quality that all successful people have to have. You have to believe that something different than what has happened for the last 50 million years of history. You have to believe that something different can happen.

Being realistic is the most commonly traveled road to mediocrity. Why would you be realistic? What’s the point of being realistic? It’s unrealistic to walk into a room, flip a switch and lights come on. That’s unrealistic – fortunately, Edison didn’t think so. It’s unrealistic to think you are going to bend a piece of metal and fly people over an ocean in that metal. That’s unrealistic but fortunately the Wright brothers and others didn’t believe that and it just seems like such a ridiculous idea to me to embrace the idea that it’s not going to happen - that’s not real. – Will Smith
