Know or listen to those who know.

The dog that trots about finds a bone.

Either you run the day or the day runs you.

To know oneself, one should assert oneself.

Always desire to learn something useful.

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

Begin to be now what you will be hereafter.

You never know what motivates you.

The most effective way to do it, is to do it.
