The dog that trots about finds a bone.
Without hard work, nothing grows but weeds.
Know or listen to those who know.
After a storm comes a calm.
Always desire to learn something useful.
Never complain and never explain.
What you do today can improve all your tomorrows.
Expect problems and eat them for breakfast.
You never know what motivates you.
By failing to prepare, you are preparing to fail.
I think space will be conquered through the mind rather than the clumsy medium of space travel.
