Go for it now. The future is promised to no one.
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.
You never know what motivates you.
Expect problems and eat them for breakfast.
To be a good loser is to learn how to win.
Who seeks shall find.
The most effective way to do it, is to do it.
It's always too early to quit.
Without feeling abashed by my ignorance, I confess that I am absolutely unable to say. In the absence of an appearance of learning, my answer has at least one merit, that of perfect sincerity.
