If you're going through hell, keep going.
Expect problems and eat them for breakfast.
It's always too early to quit.
Who seeks shall find.
Things do not happen. Things are made to happen.
The secret of getting ahead is getting started.
If you think you can do it, you can.
You never know what motivates you.
Without hard work, nothing grows but weeds.
I can, therefore I am.
I used to spend every morning in detention at my old school.
