I would never want to retire. This whole series of articles is silly. Let alone that if you're the kind of person that wants to do nothing for the rest of your life there is an even smaller chance of making it in building a startup.
Why can't someone interested in a future in philanthropy, volunteerism, family building, etc., succeed at building a startup?
None of them are likely to be income-generating ventures, meaning for all intents and purposes, it's a life of retirement. Retirement does not imply doing "nothing" for the rest of one's life.
