Quality is not an act, it is a habit.
The most effective way to do it, is to do it.
If you think you can do it, you can.
If you're going through hell, keep going.
Know or listen to those who know.
Always desire to learn something useful.
Well done is better than well said.
Who seeks shall find.
Go for it now. The future is promised to no one.
Without hard work, nothing grows but weeds.
I worked hard learning harmony and theory when I was growing up in Chicago in the 1920s.
