Possible and Impossible

..taken from a conversation at work.

Erik: If I told you it was possible to make fire come out of your hand, what would you say?

Co-worker: I would tell you it is impossible.

Erik: Why is it impossible?

Co-worker: Because no one can make fire come from thier hand. Unless you know something I don't.

Erik: I think we all really know. In my opinion, I believe it is just as possible to make fire come from ones hand as it is to believe it is impossible.

Co-worker: Huh?...

Erik: Think about it for a while (an infinate number of doors will open up for you).
