The dog that trots about finds a bone.
Do not weep do not wax indignant. Understand.
Without hard work, nothing grows but weeds.
What you do today can improve all your tomorrows.
You never know what motivates you.
If you're going through hell, keep going.
Things do not happen. Things are made to happen.
The secret of getting ahead is getting started.
Who seeks shall find.
I can, therefore I am.
I think space will be conquered through the mind rather than the clumsy medium of space travel.
