"Never be in a hurry; do everything quietly and in a calm spirit. Do not lose your inner peace for anything whatsoever, even if your whole world seems upset."
--St. Francis de Sales
The key is to do everything you can with what you have and when you have it. Rushing and procrastinating are both destructive, and one often leads to the other. A person who procrastinates, will later find himself rushing to meet deadlines. A person who is rushing to meet deadlines eventually burns out, which leads back to procrastination. If you find yourself in one of these cycles, stop it where you are. You can't rush or wait your way out of it, you must simply stop doing either. Instead simply do what you can with what you have without rushing and without waiting. If you do this, your efficiency and energy will increase and you will find yourself accomplishing far more than you thought possible.
