I can, therefore I am.

To know oneself, one should assert oneself.

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

If you're going through hell, keep going.

Do not weep do not wax indignant. Understand.

Begin to be now what you will be hereafter.

What you do today can improve all your tomorrows.

The dog that trots about finds a bone.

Without hard work, nothing grows but weeds.
