It's always too early to quit.

By failing to prepare, you are preparing to fail.

The dog that trots about finds a bone.

Be thine own palace, or the world's thy jail.

To know oneself, one should assert oneself.

Either you run the day or the day runs you.

Know or listen to those who know.

If you've got a talent, protect it.

Be gentle to all and stern with yourself.
