If you think you can do it, you can.
Well done is better than well said.
It's always too early to quit.
Always desire to learn something useful.
The wise does at once what the fool does at last.
The dog that trots about finds a bone.
Quality is not an act, it is a habit.
Never complain and never explain.
Know or listen to those who know.
To know oneself, one should assert oneself.
I highly recommend worrying. It is much more effective than dieting.
