Like my friend Warren Buffett, I feel particularly lucky to do something every day that I love to do. He calls it 'tap-dancing to work.

I never took a day off in my twenties. Not one. And I'm still fanatical, but now I'm a little less fanatical.

The First 40 hours of work per week are for survival. Everything after that is for success.

Nature has not intended mankind to work from eight in the morning until midnight without that refreshment of blessed oblivion which, even if it only lasts twenty minutes, is sufficient to renew all the vital forces.

The perils of overwork are slight compared with the dangers of inactivity.

Work while others are wishing.
