Never complain and never explain.
Either you run the day or the day runs you.
I can, therefore I am.
Well done is better than well said.
The dog that trots about finds a bone.
By failing to prepare, you are preparing to fail.
It's always too early to quit.
Know or listen to those who know.
Begin to be now what you will be hereafter.
Be thine own palace, or the world's thy jail.
I travel all over the country making speeches for people I believe in.
Teaching was the hardest work I had ever done, and it remains the hardest work I have done to date.
