You will find it will almost always be more comfortable to sit on the sidelines and critique the builders from afar. But at the end of the day, the people who make a difference, the people who shape history, are not the haters.

It doesn't make a difference what temperature a room is, it's always room temperature.

I believe in work. If somebody doesn't create something, however small it may be, he gets sick. An awful lot of people feel that they're treading water -- that if they vanished in smoke, it wouldn't mean anything at all in this world. And that's a despairing and destructive feeling. It'll kill you.
