Be gentle to all and stern with yourself.
If you're going through hell, keep going.
Only the educated are free.
You never know what motivates you.
What you do today can improve all your tomorrows.
Quality is not an act, it is a habit.
To be a good loser is to learn how to win.
Be kind whenever possible. It is always possible.
Leap, and the net will appear.
It's always too early to quit.
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.
