Physical Fitness
"Physical fitness is not only one of the most important keys to a healthy body, it is the basis of dynamic and creative intellectual activity. The relationship between the soundness of the body and the activities of the mind is subtle and complex. Much is not yet understood. But we do know what the greeks knew: that intelligence and skill can only function at the peak of their capacity when the body is healthy and strong" - President John F. Kennedy 

This quote means that if you are healthy your body works more often. If you are just a lazy bum, you dont get any work done. Always manage to keep yourself healthy and fit. Never be lazy and just stop doing the stuff, keep in mind for a better life you need to be healthy. Keep track of yourself and your health. Always exercise keep yourself fit , dont eat to much junk food. Eat only when you need to. Join a sport to keep your self healthy. Dont be like other people who are just lazy and dont care about anything.
