It's always too early to quit.

To know oneself, one should assert oneself.

The dog that trots about finds a bone.

If you're going through hell, keep going.

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

If you've got a talent, protect it.

Without hard work, nothing grows but weeds.

You never know what motivates you.

Quality is not an act, it is a habit.
