A pint of sweat will save a gallon of blood. — George Patton

My Take – Proper practice prevents piss poor performance.  Work on developing skills and good habits and then ingrain them into your default method so that you do them without thinking about them.  Take the time now, when nothing is an emergency, to make sure you have what you need and what you have is in good working order.  Learning, practicing, and preparing can make even the hardest tasks a lot easier.
