My dad was a singer in a band and neither of my parents went to college, and I ended up getting into Harvard and was the first person in my family that went to college and it happened to be Harvard.
The best thing I ever learned from my dad was he knew he wasn't the best of singers, but he always knew he was a great entertainer, and I always thought that was a good concept to bring along, that ultimately acting is an entertainment art and you have to be aware of the fact that you want people to be excited to be watching you.
My dad's era believed that there was something noble in being a good guy - the kind of guy that lived straight and narrow, told the truth, and stood up for what he believed was right.
If you force yourself to smile, within a couple minutes, you feel happy.
