If you're going through hell, keep going.
Know or listen to those who know.
To be a good loser is to learn how to win.
Without hard work, nothing grows but weeds.
Always desire to learn something useful.
By failing to prepare, you are preparing to fail.
Be gentle to all and stern with yourself.
You never know what motivates you.
Well done is better than well said.
Go for it now. The future is promised to no one.
