Lovell is a recipient of the Congressional Space Medal of Honor and the Presidential Medal of Freedom. He is one of only 24 people to have flown to the Moon, the first of only three people to fly to the Moon twice, and the only one to have flown there twice without making a landing. Lovell was also the first person to fly in space four times... (wikipedia)

The lunar flights give you a correct perception of our existence. You look back at Earth from the moon, and you can put your thumb up to the window and hide the Earth behind your thumb. Everything you've ever known is behind your thumb, and that blue-and-white ball is orbiting a rather normal star, tucked away on the outer edge of a galaxy.
There are people who make things happen, there are people who watch things happen, and there are people who wonder what happened. To be successful, you need to be a person who makes things happen.
Be thankful for problems. If they were less difficult, someone with less ability might have your job.
Boys like either dinosaurs or airplanes. I was very much an airplane boy.
I was only a hero by default. The flights were few and far between. There weren't that many astronauts. The moon flights were so interesting and exciting.
