I have a day job that I enjoy and is rewarding. Plus my company pays for all training and career development (completely unrelated to photography) which I highly value. so unless that all changes, I'm not sure I'll want to quit.
Other big reason is that I really enjoy having creative freedom with the weddings I accept, with the prices I can charge, marketing experiments, etc. It's taken me a few years to balance both.. but I'm at a point which is pretty good. No reason to mix it up, at least not for the next ~2 years.
I think about it all the time, though. Going full time photography. I know it would be a rush, challenging, fulfilling, exciting.. and I remind myself that it's a great option if I ever begin to dislike my day job.
