Early in life, I had a small amount of artistic success (music). Though I probably couldn't have gone big with it, I did enjoy some amount of regional fame. Hard work, definitely an accomplishment, and I built several friendships out of it that have lasted over two decades (as well as lots that did fade away in time).
Similar thing with a startup I cofounded several years ago--the problem we were solving had me out in the public eye for a while, and I ended up building friendships with lots more people...people I'm still friends with.
And you know, if not for the relationships I build, some of which turned into lasting friendships, I wouldn't have had the success in the first place.
Nothing goes anywhere in life without people around you, helping you out. If you don't treat those people as the most important part of whatever you're doing, you're doing it wrong.
