Be gentle to all and stern with yourself.
The secret of getting ahead is getting started.
Do not weep do not wax indignant. Understand.
It's always too early to quit.
Wherever you are - be all there.
If you're going through hell, keep going.
If you've got a talent, protect it.
Leap, and the net will appear.
If you can dream it, you can do it.
Who seeks shall find.
You can be in Tokyo or Alberta at four in the morning in your hotel and you can still practice if you feel like it. A trombone cannot do that at four in the morning.
