If you think you can do it, you can.
Quality is not an act, it is a habit.
Do not weep do not wax indignant. Understand.
Who seeks shall find.
After a storm comes a calm.
Only the educated are free.
Know or listen to those who know.
The secret of getting ahead is getting started.
Go for it now. The future is promised to no one.
If you're going through hell, keep going.
I think space will be conquered through the mind rather than the clumsy medium of space travel.
