It will most likely wreck your life like others already said because of the fact its something that is not should be done for the profit.
I think that if you do it will ruin your life without any doubts.
What you are saying is that you are only representing on the number of people who have ruin their life because of gambling, if gambling is really not a good way to be part of entertainment then the majority of the gamblers will not patronize gambling sites anymore and quit, but what happen now is that gambling sites are so profitable because many gamblers want to spend to enjoy it.
Correct, this is the same as alcohol really, a significant percentage of the people or more can consume alcohol in a responsible manner but a lesser percentage of people become addicted to it, if you gamble just a few times and just for fun you are going to be fine.
It it just a matter on how you can tolerate yourself, in gambling there are principles that we need to follow which should be applicable for everybody in gambling, bet what you can afford to lose, if we were able to follow that throughout our gambling career, then there will be no problem.
