Slightly longer version. I grew up thinking I was hot s#1t. You know smart, hard working, loving family (with its own annoying hateable quirks), destined to do great things, Yada Yada yada. You can see where this is going.
Many things didn't pan out and some things lucked out. Sadly my speciality had nothing to do with it. Heck with a lot of help and support and mentoring etc I was guided to see that the luckiest of luckiest rarely deserve their good fortune any more than the most downtrodden of the downtrodden deserved their misfortune. So much so often comes down to environment and luck.
While we are here might as well enjoy the ride, work on things you are passionate about, cherish loved ones and don't harm others (atleast transitively by X degrees).
