Why didn't you do a poll Larry?
Obviously, my answer is that I KNOW AP is possible. And because someone like me, with limited abilities and smarts, can and has had some level of success, I know that almost anyone that was willing to dedicate themselves to putting in a little time and effort could succeed.
I wouldn't and don't recommend anyone attempt to make a living doing so, not that it's that hard, given the right circumstances, but it's just not for everybody and there is a saying that "if you can make a living APing, then you could have made more money doing something else".In other words, those of us that choose APing for a living, it's not JUST about the money. You have to have some passion about making a living this way.
But aside from making a living, I think almost anyone (problem gamblers aside) could easily turn their occasional casino visits from a negative EV experience to a positive EV experience, with very little effort.
