Either you run the day or the day runs you.
What you do today can improve all your tomorrows.
If you think you can do it, you can.
Problems are not stop signs, they are guidelines.
If you can dream it, you can do it.
By failing to prepare, you are preparing to fail.
It's always too early to quit.
After a storm comes a calm.
If you're going through hell, keep going.
If you've got a talent, protect it.
I think space will be conquered through the mind rather than the clumsy medium of space travel.
