Wherever you are - be all there.
After a storm comes a calm.
Be gentle to all and stern with yourself.
Quality is not an act, it is a habit.
Either you run the day or the day runs you.
The most effective way to do it, is to do it.
Expect problems and eat them for breakfast.
If you're going through hell, keep going.
Know or listen to those who know.
Always desire to learn something useful.
I think that somebody with the resources and innovation and the idea is going to come out of nowhere and come up with a successful space travel program.
