Know or listen to those who know.
Expect problems and eat them for breakfast.
Begin to be now what you will be hereafter.
It's always too early to quit.
Go for it now. The future is promised to no one.
If you can dream it, you can do it.
If you think you can do it, you can.
To be a good loser is to learn how to win.
The most effective way to do it, is to do it.
