Can you expand on your experience? any particular lessons you learned? Seems like you had all the conventional marks of success, I find it hard to believe that that was all for naught.
It wasn't all for naught, but success is not going to completely fill the hole inside. Lesson? It's simple, don't work all the time and neglect your family. I cringe everytime I hear Musk talking about working 100 hours a week. He has kids by previous marriages afaik, but it sounds to me like he's not much more than a sperm donor. He's a terrible role model for fathers. I worked probably 70 to 80 hours a week for 9 years. My son has a lot of complaints about me not being there and he's right. The only thing I can say to him is that I'm here now.
Maybe it was whose definition of “success” the person was pursuing…conventional definitions are conventional because people accept them without deep reflection on whether they are right for them. They are easier to adopt than to question.
Or a problem with winning the rat race is you have to be a rat.
If you've seen Breaking Bad (if not, I'm not spoiling much) there is a scene where he tells his wife "I did it all for the family" and she disgustingly turns her head away and says something like "You did it for your own ego. You didn't care about us." It's kind of like that.
