I never saw a problem that I did not attempt to solve by mechanical means.

Patience is the most important skill in life.

The best revenge is massive success.

The only way to do great work is to love what you do.

If you're trying to achieve, there will be roadblocks. I've had them; everybody has had them. But obstacles don't have to stop you. If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it, or work around it.
