People who are unable to motivate themselves must be content with mediocrity, no matter how impressive their other talents.

Men of age object too much, consult too long, adventure too little, repent too soon, and seldom drive business home to the full period, but content themselves with a mediocrity of success.

I'm for people bettering themselves, no matter who they are and where they are, doing all they can to be all they can be.

You must capture and keep the heart of the original and supremely able man before his brain can do its best.

The men who have succeeded are men who have chosen one line and stuck to it.

No man will make a great leader who wants to do it all himself or get all the credit for doing it.
