By failing to prepare, you are preparing to fail.
Well done is better than well said.
Without hard work, nothing grows but weeds.
Only the educated are free.
Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
If you're going through hell, keep going.
Quality is not an act, it is a habit.
What you do today can improve all your tomorrows.
Who seeks shall find.
But to me the bottom line is the more education you can give yourself, and the more preparation you can do, the less chance of failing.
