Bravery comes along as a gradual accumulation of discipline - Buzz Aldrin

The airless moon receives more than 13,000 terawatts of solar power. Harnessing just one percent of that sunlight could satisfy Earth’s power needs.

To succeed in any environment, you have to believe in yourself. You must have an unshakable confidence in your own ability to achieve your goals and get the job done.

Seeking help when I was suffering with depression after returning from the Moon was a lifesaver for me — perhaps, literally. Several people in my family, including my own mother, had committed suicide, so I wondered if there was a genetic predisposition that might cause me to follow their examples. Fortunately, I found excellent doctors and friends who encouraged me and helped me to recognize that I was not trapped by the past, that I could be responsible for my own decisions, and that my emotional health was much more important than my career.
