There seems to be this myth that your purpose in life is tied directly to your job (ie, what’s your dream job? what do you want to be when you grow up?), but for the majority of people, I don’t think this is true. I’ve heard arguments that if everyone stopped working, they’d devolve into depressed and lazy alcoholics…but that’s already happening to people who work full time. So, what would you do with your time if you didn’t have to work to survive? Bear in mind, that if you actually enjoy what you do for a living, you could still continue to do that even if you didn’t have to to survive.
Personally I would pursue more creative stuff. Maybe learn how to draw. I’d spend more time playing video games. I’d travel. And I would spend more time with the people that I love.
