Not easy. Many hassles and much time spent in unpleasant, hostile environment
ok; is it an easy way to make a living??
It depends on what else you have done or are able to do. Your age, work experience, life expectations, family situation, need for health insurance, and other factors must be figured in. There is no simple answer. For some it is the most enjoyable and best-paying thing they have ever done. For others, it is drudgery; they hate going to casinos, and do it only for the money with no enjoyment.
It is easy compared to, say, construction work or other hard physical labor. It is stress-free compared to what I imagine an air traffic controller, brain surgeon, or nurse goes through every day. But advantage play is hard compared to some middle management position in a do-nothing government agency or a large corporation, where you have to do little more than show up, attend a few useless meetings, and line up at the feeding trough on payday.
It depends on your own temperament, too. I despise casinos. Almost all full-time or serious part-time players despise casinos. I despise them more every day. Therefore, I enjoy taking their money more than I used to. But I don't need to and am not willing to put in as many hours as I used to.
If you'll post something about your life situation, without giving up enough information to identify you, I'll be glad to make more comments or suggestions.
