It's always too early to quit.

Know or listen to those who know.

Begin to be now what you will be hereafter.

Either you run the day or the day runs you.

What you do today can improve all your tomorrows.

If you think you can do it, you can.

Leap, and the net will appear.

The wise does at once what the fool does at last.

If you've got a talent, protect it.
