So I would say you are burned out. Sell the business, start another one where you want to put in energy again. What you lack is passion, not experience. And usually about the most useless advice I get is from MBA. An MBA is for a person who wants to learn about running a business, not actually run one. And if you can’t find the passion to do it yourself, team up with someone else. Once you’ve worked for yourself it’s damn difficult to work for someone else. And really you shouldn’t have to. Having run your own business you know more than they do. I started one startup business at 45 and my arcade at 51. I enjoy both and I want to be there. And I do this all the while being a doctor that I also enjoy. Your skill set can’t be easily replicated. Put it to use doing something you want to do, not something you think you have to do. Life is too short to not do what you want to do when you have the capability to direct your own life. Good luck.
