It's always too early to quit.

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

To know oneself, one should assert oneself.

Know or listen to those who know.

You never know what motivates you.

If you can dream it, you can do it.

Begin to be now what you will be hereafter.

If you're going through hell, keep going.

The dog that trots about finds a bone.
