The Health Confusion

Why is it that when something's good for you it always hurts in some way or the other. For instance, food doesn't "hurt", but most of the "good foods" taste disgusting, while most of the food that's bad for you is extremely tasty and sometimes very filling. The same's for exercise. No one every got a six pack by sitting on the couch eating cheetos and watching reality tv. That would be too easy. If you want to look like Rocky Balboa then you have to work hard like Rocky Balboa. This concept is the same for most good things in life. Those who we consider "successful" didn't get to where they are by taking the easy, "fun" route. No they put their blood, sweat, and tears into what they were trying to accomplish and thereby earned their success.
