"Genetics" are an excuse in most cases... you cannot outgrow your height or your frame, but any human being can make the best of what they have. It is either through ignorance of the methods to achieve this, or through sheer laziness that "genetics" are not overcome. Anybody can have a six-pack, but many people are unable to conquer their addictions to food, alcohol, drugs, etc etc.... and that's fine too. Live your life the way you wanna, and find happiness in whatever makes you happy. Just don't bash people who work hard to achieve the bodies they have and find happiness in that. :]
