Investment wise. Get good, sell the skill, make 10 mil and repeat. Soon to be rich enough to start buying out other skills or one main skill you enjoy doing lolol. That's one way to look at it. But selling your "passion" at the cost of 10 mil. I'd be really lonely. I mean, there's other things I do enjoy doing but I'm not "passionate" about them. For example, I do enjoy competitive fighting games but not to the point that I'm passionate enough about it to want to be a professional player winning big tournaments. I feel for people or for me, we all have many things we enjoy but "passion" feels like something else.
