Be kind whenever possible. It is always possible.
The dog that trots about finds a bone.
Well done is better than well said.
Never complain and never explain.
Always desire to learn something useful.
I can, therefore I am.
Either you run the day or the day runs you.
Be gentle to all and stern with yourself.
To know oneself, one should assert oneself.
To be a good loser is to learn how to win.
I once bought my kids a set of batteries for Christmas with a note on it saying, toys not included.
