The glow of satisfaction which follows the consciousness of doing our level best never comes to a human being from any other experience.
Success is the child of drudgery and perseverance. It cannot be coaxed or bribed; pay the price and it is yours.
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.
Resolve that whatever you do, you will bring the whole man to it; that you will fling the whole weight of your being into it.
Power gravitates to the man who knows how.
You cannot measure a man by his failures. You must know what use he makes of them. What did they mean to him. What did he get out of them.
There is an infinite difference between a little wrong and just right, between fairly good and the best, between mediocrity and superiority.
