If you think you can do it, you can.
Begin to be now what you will be hereafter.
If you can dream it, you can do it.
Without hard work, nothing grows but weeds.
Know or listen to those who know.
Never complain and never explain.
To be a good loser is to learn how to win.
It's always too early to quit.
The wise does at once what the fool does at last.
Be kind whenever possible. It is always possible.
