Dr. Buzz Aldrin served as lunar module pilot for Apollo 11, the first
manned lunar landing mission.

'My failures have led to my successes,' 
the astronaut writes in his new memoir

If you want to do something significant, something noble,
something that perhaps has never been done before, you
must be willing to fail. And don’t be surprised or devastated
when you do. It is not the end of the world, and untold
numbers of people have experienced major failures and
have come back from them, not only as more successful,
but also as better, stronger people./.../
