If you're going through hell, keep going.
Be kind whenever possible. It is always possible.
Well done is better than well said.
After a storm comes a calm.
Always desire to learn something useful.
It's always too early to quit.
What you do today can improve all your tomorrows.
The wise does at once what the fool does at last.
Only the educated are free.
I can, therefore I am.
The one phrase you can use is that success has a thousand fathers, and failure is an orphan.
