I can, therefore I am.
What you do today can improve all your tomorrows.
Go for it now. The future is promised to no one.
Well done is better than well said.
If you can dream it, you can do it.
Things do not happen. Things are made to happen.
It's always too early to quit.
Begin to be now what you will be hereafter.
Expect problems and eat them for breakfast.
The secret of getting ahead is getting started.
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.
