Don't let someone who gave up on their dreams talk you out of going after yours.
You measure success by how much good you do for others.
Whether you respond to life or react to life determines how far you're gonna go in life.
When you have nothing to hide you have nothing to fear. When you do the right things in the right way you have nothing to lose because you have nothing to fear.
Expect the best. Prepare for the worst. Capitalize on what comes.
There's never been a doctor who served many patients who, despite their best efforts, did not lose some of them to death. But they understood that was part of life itself.
