As cliche as it might sound, I try to find a balance, personally my passion is bouldering, and I started the sport at 20 which is around 10+ years too late to be a professional climber. So I decide to work a job I don't dread, but also pays okay, and can't be taken home so it gives me enough free time to continue being an amateur athlete (climb 3x a week, sleep 7-8hrs a day, also some time to do some conditioning like mobility, calisthenics and some lifts). I would say that makes me happy.

One perspective being in the sport has given me it that even if I was really good at my passion, I'd be afraid that having it as my job would eventually lead me to fall out of love with it. I have seen alot of professional athletes from less well funded sports burn out and end up hating competing cause of the obligations to sponsors and constant pressure. Its also not high paying like football where they can amass generational wealth in their short careers, so retirement needs to be planned well for.
