Gambling will help you in your life in many ways. Entertainment, thrill, joy or winning etc etc. But moreover, the winnings will make your life more happy by adding a richness in your daily life. Unless you loose and that is inevitable. So gambling is good for only those who are not worried about losing their money.
But the big question is, do you always win? No, right? Because most of the time in gambling, we lose, and we can't change that fact because that's how it works because of this house edge. So, if we are just doing gambling just because we want some entertainment, then why not just watch some funny videos or go to the circus or something, in that way, you could really find the "
Entertainment" that you were saying.
And not on gambling which you could lose your money just for this "entertainment" nonsense, because how could be this entertaining if we are losing most of the time, it doesn't make sense.
