It's always too early to quit.

You never know what motivates you.

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

To know oneself, one should assert oneself.

To be a good loser is to learn how to win.

Problems are not stop signs, they are guidelines.

The secret of getting ahead is getting started.

The dog that trots about finds a bone.

Begin to be now what you will be hereafter.
