At first the research did not seem to be particularly interesting – I carried out a systematic search for processes that might destroy the CFCs in the lower atmosphere, but nothing appeared to affect them. We knew, however, that they would eventually drift to sufficiently high altitudes to be destroyed by solar radiation. The question was not only what destroys them, but more importantly, what the consequences are.

The world would say it was failure. But the difference was so small between us. They played great, but they lost.

It is not the critic who counts; not the man who points out how the strong man stumbles or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, and comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows the great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who know neither victory nor defeat.

So we had to take this special exam and I flunked it. Erv Upton passed it, and I was scared. I figured if I failed it, I wouldn’t have any chance of getting in. So I failed it beautifully. ...

Finding gratitude and appreciation is key to resilience. People who take the time to list things they are grateful for are happier and healthier. It turns out that counting your blessings can actually increase your blessings. My New Year's resolution this year is to write down three moments of joy before I go to bed each night. This simple practice has changed my life. Because no matter what happens each day, I go to sleep thinking of something cheerful.
