Well, there is indeed a long path to being rich and I actually witnessed a handful of people who acquired wealth by taking this path. From rags to riches, and I think it isn't a coincidence that they don't actually gamble. Instead, they save and invest it to put up a business. BUT! don't get me wrong, I don't mean that when someone engaged into gambling, they will automatically taking the short cut to poverty lol. With proper moderation and self control, gambling is nothing but just a past time hobby. However, we've seen hundreds if not thousands of people became broke because of excessive gambling behaviours. But, I haven't seen someone who get broke by dedicating their lives into working hard. Some may not be able to reach the level of being rich, but at least they ain't broke either.
In the end, there will be gamblers who go bankrupt, and there will be gamblers who are mediocre even though they have the same gambling activities. it's just that some gamblers become excessive in their gambling which makes gamblers eventually go bankrupt. while other gamblers may be able to control their gambling allocation well so that their finances will not be burdened by their gambling. even though they don't become rich, at least gamblers who are disciplined enough will not be disturbed by their finances. and those who are negligent must bear the risk.
