If you think you can do it, you can.
I can, therefore I am.
Without hard work, nothing grows but weeds.
Expect problems and eat them for breakfast.
The wise does at once what the fool does at last.
If you're going through hell, keep going.
Either you run the day or the day runs you.
Know or listen to those who know.
Be gentle to all and stern with yourself.
Only the educated are free.
The world is divided into two categories: failures and unknowns.
Knowledge is ancient error reflecting on its youth.
God invented concubinage, satan marriage.
