Too much of everything is bad including excessive gambling, it can lead to addiction without the gambler knowing how he got to that stage. The best way to gamble is to be in control of your emotions and use small amounts to gamble, if you can do this you won't be addicted. Some people see gambling as a short cut to riches where they will win big after some trials, this mindset is wrong, gambling wins are by luck and you don't know when it can happen or if it will happen. Enjoy yourself in gambling with small amounts and take wins if you're lucky, if not you should move on and try another time.
Too much of everything is bad, but another context is that if you want to make money from gambling, you need to spend more money, and i noticed that those that are making more money when it comes to gambling are those that are ready to spend because consistency will cost you a lot, but at the same time it pays sometimes and this why you can not even compare your gambling habit with that of others because they are ready to spend more and they are ready to risk a lot of money, just that when they eventually get a win, it will eventually cover for all ir losses. But before that happens, the bettor must have spent a lot of money, and you will see that the bettor is becoming strategic about gambling. To me, that is the best way to actually gamble.
