It's always too early to quit.
Who seeks shall find.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
Do not weep do not wax indignant. Understand.
Leap, and the net will appear.
Begin to be now what you will be hereafter.
To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
Without hard work, nothing grows but weeds.
Imagination! Imagination! I put it first years ago, when I was asked what qualities I thought necessary for success on the stage.
