Being happy is a serious handicap

There is a teenage boy I know who worries me quite a lot. He was born to a good family with plenty of money. He is extroverted and optimistic; people appear to like him. He’s relatively easy on the eye and reasonably bright. His health is good and he can kick, hit and catch balls of various shapes and sizes. He does not smoke, or take drugs, or do any more binge drinking than the next person.
