The busy man is never wise and the wise man is never busy.

There is no such thing as a lazy person; he is either sick or uninspired.

No man is the wiser for his learning.

No one is satisfied with his fortune, nor dissatisfied with his intellect.

No man ever followed his genius til it misled him.

No man has a good enough memory to be a successful liar.

No public cause deserves the unlimited allegiance of an intelligent man.

The self-surmounter can never put up with the man who has ceased to be dissatisfied with himself.

There has never yet been a person in our history who led a life of ease whose name is worth remembering.

No one, however smart, however well educated, however experienced, is the suppository of all wisdom.

an intelligent man cannot become anything seriously, and it is only the fool who becomes anything.

There is no man living who isn't capable of doing more than he thinks he can do.

The man who never reads will never be read; he who never quotes will never be quoted. He who will not use the thoughts of other men’s brains, proves that he has no brains of his own.

No one is ever satisfied where he is.
