Be gentle to all and stern with yourself.
Always desire to learn something useful.
I can, therefore I am.
It's always too early to quit.
If you think you can do it, you can.
Know or listen to those who know.
After a storm comes a calm.
The wise does at once what the fool does at last.
If you've got a talent, protect it.
Either you run the day or the day runs you.
I pick projects according to how fascinating they are to me, and it has resulted in a broad reach. My records are actually in five different sports: balloons, airplanes, airships, gliders, and sailboats.
