There's a certain stage one would get to in life and some kind of activity won't be carried out again. It works same for everyone unless there's an addiction to the act. Addictiveness is dangerous as in terms of gambling, yes, there'll be trials and errors and times for wins and losses but if after a period of time, rich or not, one doesn't learn to curtail the act, it only means that there and then, there's an addiction to it.
There's been times where after so many trials and losses, finally, gamble pays huge, for some certain people, that'll be the end of their gambling quest as they've achieved what they've been scouting for and for some, greed sets in and they end up putting back the extra wealth gathered to risk the chance of it multiplying and in 9 out of 10chances, an extra loss is incurred. It's not so right to gamble but if you have to gamble, there should be responsibility to it. Too much of everything is not good as they'd say.
