It's always too early to quit.

Go for it now. The future is promised to no one.

To know oneself, one should assert oneself.

Quality is not an act, it is a habit.

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

Know or listen to those who know.

The dog that trots about finds a bone.

Begin to be now what you will be hereafter.

The secret of getting ahead is getting started.
