There's a lot more to happiness than fun, success and money, yes. Thanks for pointing that out and supplying so much valuable (and applicable) information!
Your story with the lottery winner reminded my of that scientifical study where they surveyed the connection between income and happyness, and they found that up to a years wage of somewhere around 60k dollars, people really got happier, as they had to worry less about daily needs. After that point, however, there was no connection whatsoever between income and happyness (I think to remember it even slightly decrease in average for the very rich, but I might be mistaken here).
This demonstrates that often, we set wrong goals and expectations that bar us from becoming happy.
So true!
Thank you for taking the time to read and comment @sco :)
