I am in college now, have a full-time job, and breed snakes on the side. In my opinion, you should stay in school. Think about your future. You don't know what is going to happen with snakes. What if in a few years they ban them? What if in a few years all are worth $20? You just never know. You can be certain that if you stay in school, and get a degree, that you will be able to successfully get a good job.
Do what you will, but think about your future first. You may make a fair about of money now, but what about if you decide to get married, have kids, but a house and a few new cars. Will you pay be enough then?
