IMO success is a personal thing, and generally, it's what makes you happy. The societal version of success is to be rich and be full of money and be super high on the corporate ladder and all that stuff, but really if you're not happy then what's the point? I put myself more like the 2nd person in that video but I consider myself successful, I'm happy, not really all that stressed, but still have the main things that I've always wanted since I was a kid. Got a house, car, decent job, close to family, and generally in a low stress life setting. I pretty much reached the peak of where I've always wanted to be, anything else I achieve in the future is just a bonus. Of course human nature is we always want more, but I'd have to say I'm happy where I am now and that counts more for whatever society thinks is considered success.
