I find my greatest pleasure, and so my reward, in the work that precedes what the world calls success.

Those who cannot work with their hearts achieve but a hollow, half-hearted success that breeds bitterness all around.

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 secret to success is to make your vocation your vacation.

The first requisite for success is to develop the ability to focus.

By working faithfully eight hours a day, you may eventually get to be a boss and work twelve hours a day.
