Well done is better than well said.
Know or listen to those who know.
Do not weep do not wax indignant. Understand.
The secret of getting ahead is getting started.
Who seeks shall find.
Begin to be now what you will be hereafter.
Go for it now. The future is promised to no one.
Expect problems and eat them for breakfast.
Be thine own palace, or the world's thy jail.
Without hard work, nothing grows but weeds.
I worked hard learning harmony and theory when I was growing up in Chicago in the 1920s.
