Never complain and never explain.
If you've got a talent, protect it.
I can, therefore I am.
To know oneself, one should assert oneself.
By failing to prepare, you are preparing to fail.
The dog that trots about finds a bone.
Only the educated are free.
Be thine own palace, or the world's thy jail.
The secret of getting ahead is getting started.
Well done is better than well said.
