Our thoughts and imaginations are the only real limits to our possibilities.

Success is not measured by what you accomplish, but by the opposition you have encountered, and the courage with which you have maintained the struggle against overwhelming odds.

All men who have achieved great things have been great dreamers.

Be larger than your task.

There's no grander sight in the world than that of a person fired with a great purpose, dominated by one unwavering aim.

A man will remain a rag-picker as long as he has only the vision of a rag-picker.

Success is the child of drudgery and perseverance. It cannot be coaxed or bribed; pay the price and it is yours.
