Be kind whenever possible. It is always possible.
Well done is better than well said.
The dog that trots about finds a bone.
If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
Always desire to learn something useful.
I can, therefore I am.
If you think you can do it, you can.
It's always too early to quit.
To be a good loser is to learn how to win.
A good teacher must be able to put himself in the place of those who find learning hard.
