My success is due more to my ability to work continuously on one thing without stopping than to any other single quality.

Success is having to worry about every damn thing in the world, except money.

Success is based on imagination plus ambition and the will to work.

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

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

I know of no single formula for success, but over the years I have observed that some attributes of leadership are universal, and are often about finding ways of encouraging people to combine their efforts, their talents, their insights, their enthusiasm and their inspiration, to work together.
