It changed my life in a way that has very little to do with my YC-funded company.
It helped me onto a path of healing and growth from chronic emotional and physical pain, and inspired me to focus on being a more rounded, grounded, decent person, rather than on simplistic notions of “success”.
It’s hard to imagine how I could have turned my life around so much, without YC.
None of these personal development practices were provided/recommended by YC, but YC gave me the confidence and self-belief to find this path and pursue it all the way, when no person or organisation had done so before, and none I know of today would give that kind of opportunity to the person I was at that time.
Of course, many organisations can help people make profound changes in their lives, and YC is not going to be the best one for everyone or even many people.
But it was the the first organisation that helped me make the changes I needed, and those changes had nothing to do with becoming (or trying to become) a tech millionaire/billionaire.
Of course, YC wants their founders to build successful companies if possible, but as I've found first-hand, they first-and-foremost care about about the founders' personal wellbeing and personal qualities.
