A mind can make a heaven out of hell, or a hell out of heaven.

A timely no beats a hasty yes.

It is a bad idea to take a thorn out of someone else’s foot and put it into your own.

It is the mind that wins or loses.

If I held all the thoughts of the world in my hand, I would be careful not to open it.

Most of one’s life is one prolonged effort to prevent oneself thinking.

No one can think a thought for me in the way that no one can don my hat for me.

Thought means life, since those who do not think so do not live in any high or real sense. Thinking makes the man.

A man is literally what he thinks.

All that you accomplish or fail to accomplish with your life is the direct result of your thoughts.
