I really don’t want to go back to college

My dream job would be a radiation therapist but maybe just maybe I could get lucky and make a career with dental assisting. To maximize my income I would need to get a lot more experience and certifications and choose a specialty.. if I put my heart into it I can get up to $25 an hour. I won’t make the most money in the world but for 1 person I think I would be able to live pretty comfortably, I don’t see myself ever getting married or having kids anyways.
