A man can wear out a particular part of his mind by continually using and tiring it, just in the same way he can wear out the elbows of his coat.

Winston Churchill

Often in the casual remarks of great men one learns their true mind in an intimate way.

The tired parts of the mind can be rested and strengthened not merely by rest, but by using other parts.

The brain can be developed just as the muscles can be, if one will only take the pains to train the mind to think.

The mind is everything. What you think you become.

A lot of people have pretty little heads, but it's difficult to find a pretty little mind.

I believe we are powerful but we don't use our minds to full capacity. Your mind is powerful enough to help you attain whatever you want.
