To know oneself, one should assert oneself.

It's always too early to quit.

The dog that trots about finds a bone.

If you can dream it, you can do it.

What you do today can improve all your tomorrows.

By failing to prepare, you are preparing to fail.

Know or listen to those who know.

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

Begin to be now what you will be hereafter.
