Be thine own palace, or the world's thy jail.
What you do today can improve all your tomorrows.
Always desire to learn something useful.
Expect problems and eat them for breakfast.
You never know what motivates you.
Either you run the day or the day runs you.
To know oneself, one should assert oneself.
Be kind whenever possible. It is always possible.
Leap, and the net will appear.
Never complain and never explain.
The thing that's tricky is sometimes the best voices - just because someone hits the big notes and sounds amazing - it doesn't necessarily mean they make the greatest artists.
