The dog that trots about finds a bone.
Go for it now. The future is promised to no one.
Without hard work, nothing grows but weeds.
I can, therefore I am.
Know or listen to those who know.
Either you run the day or the day runs you.
Never complain and never explain.
Be kind whenever possible. It is always possible.
Well done is better than well said.
Expect problems and eat them for breakfast.
But I don't think we'll go there until we go back to the moon and develop a technology base for living and working and transporting ourselves through space.
