I think this saying is crap. Go after what you want, work for it, and meet your goals. No one ever said “I don’t want to be fit anymore” and then got fit or, “I don’t want to try in my relationship” and then were happy with their partner. Whoever stopped wanting a promotion and then received it? Dumb. Make your own rules. Work hard, maintain your ethics and values, and your life will be bliss.
