Begin to be now what you will be hereafter.
If you can dream it, you can do it.
It's always too early to quit.
Leap, and the net will appear.
You never know what motivates you.
Know or listen to those who know.
The secret of getting ahead is getting started.
Either you run the day or the day runs you.
Expect problems and eat them for breakfast.
The wise does at once what the fool does at last.
