Either you run the day or the day runs you.
After a storm comes a calm.
I can, therefore I am.
Do not weep do not wax indignant. Understand.
If you can dream it, you can do it.
What you do today can improve all your tomorrows.
If you think you can do it, you can.
If you're going through hell, keep going.
Expect problems and eat them for breakfast.
