It's always too early to quit.
You never know what motivates you.
To be a good loser is to learn how to win.
Without hard work, nothing grows but weeds.
Well done is better than well said.
The dog that trots about finds a bone.
By failing to prepare, you are preparing to fail.
If you're going through hell, keep going.
The wise does at once what the fool does at last.
If you think you can do it, you can.
If the past has been an obstacle and a burden, knowledge of the past is the safest and the surest emancipation.
Power tends to corrupt, and absolute power corrupts absolutely.
