These are a few of my favourite life lessons that I learned as a result of walking on the Moon and the preparation that took us there — the guiding principles that have helped keep me going since returning to Earth. • The sky is not the limit … there are footprints on the Moon! • Keep your mind open to possibilities. • Show me your friends, and I will show you your future. • Second comes right after first. • Write your own epitaph. • Maintain your spirit of adventure. • Failure is always an option. • Practice respect for all people. • Do what you believe is right even when others choose otherwise. • Trust your gut … and your instruments. • Laugh … a lot! • Keep a young mind-set at every age. • Help others go beyond where you have gone. I hope these lessons will be as helpful to you as they have been to me. Take it from a man who has walked on the Moon: Be careful what you dream—it just might come to pass, so be prepared. Apollo is the story of people at their best, working together for a common goal. We started with a dream, and we can do these kinds of things again. With a united effort and a great team, you too can achieve great things. I know, because I am living proof that no dream is too high!
