To be a good loser is to learn how to win.
Without hard work, nothing grows but weeds.
If you think you can do it, you can.
If you're going through hell, keep going.
Begin to be now what you will be hereafter.
The wise does at once what the fool does at last.
Know or listen to those who know.
Never complain and never explain.
If you've got a talent, protect it.
Well done is better than well said.
There is as much wisdom in listening as there is in speaking - and that goes for all relationships, not just romantic ones.
