The goal is to earn money from doing things that I consider to be absolutely fun to me. So I would want to work as much as possible until I have no energy left to carry-on or when it's begining to pose health risks to me.
When it comes to working for another person's business or company, it's nothing that I plan doing for the rest of my life. In fact, I can say that it's getting closer to when I'm going to stop working for another company and focus 100% on my own business. There's nothing like retirement in my own business anyways 😂
