Sam is taking some time off to reassess his goals. He may decide that he needs to take a different approach, or he may decide that the goal was unattainable. That is all part of the process.The point is: he went for it. The same could be said for Rhea. Despite what everyone here said, they both put themselves out there, and they tried it. I would doubt that either one has any regrets.
I don't think that anyone here would question that the life of a pro pool player is less than desirable. Only very few of the truly elite actually make a decent living, but it's a constant grind. There are a lot of other ways to make money from this game, and with a little bit of business sense, the better players can find ways to make money.
This young gentleman may not make it as an elite pro player, but there is no reason that he can't form a prosperous career from this game. He seems to be in a position, with the proper attitude, to take a chance. I have no doubts that the experiences that he'll gain along the way will be invaluable. Maybe he'll burn out, maybe he won't... But that will be up to him to decide.
What is the harm in encouraging these individuals? If they fall, why not help them back up? We have nothing to lose or gain, either way. If they fail, we never hear from them again. If they succeed, they may show appreciation for our encouragement (not likely, but who cares?).
