Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Expect problems and eat them for breakfast.

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

It's always too early to quit.

The dog that trots about finds a bone.

If you've got a talent, protect it.

Begin to be now what you will be hereafter.

By failing to prepare, you are preparing to fail.
