By failing to prepare, you are preparing to fail.
If you're going through hell, keep going.
If you think you can do it, you can.
Always desire to learn something useful.
Only the educated are free.
The wise does at once what the fool does at last.
I can, therefore I am.
Expect problems and eat them for breakfast.
Never complain and never explain.
You never know what motivates you.
Strange as it may seem, no amount of learning can cure stupidity, and formal education positively fortifies it.
