Steve Jobs' 2005 Stanford commencement speech - Stay Hungry, Stay Foolish!

When you're young, you look at television and think, There's a conspiracy. The networks have conspired to dumb us down. But when you get a little older, you realize that's not true. The networks are in business to give people exactly what they want. That's a far more depressing thought. Conspiracy is optimistic! You can shoot the bastards! We can have a revolution! But the networks are really in business to give people what they want. It's the truth.
Wired, 1996.

Don’t be trapped by dogma — which is living with the results of other people’s thinking.
Steve Jobs
