note that this example isn't doing these things professionally, but leveraged them to get into a good school, which nets a lot of valuable connections... it's not all or nothing, this person will be fine even if they don't become a pro tennis player
also I hear you on the suicides, but I grew up in a much poorer background and those are just overdoses in my situation.... there's easily a dozen kids in my graduating class that weren't pressured to do anything, had no idea what to do, and got addicted to drugs that killed them
there's no single right path
