Gambling have thought me a lot of lessons and from those lessons I have build long term experience and one of the things I most not do is to gamble when I am not in the right frame of mind, because when you are under any form of pressure, you can easily get carried away into believing that you may possibly make off some money from gambling by risking more that you can afford, this is what have lead many gamblers into bad situations such as addictions and debts on the long run.
Gambling should be based on fun and nothing more because regardless of how much desire we have, if that day is not our lucky day, you will still lose, which is why we advice that gamble with only an amount that you can afford to lose and be comfortable with.
Your point of view is absolutely correct, as a gambler it is better to gamble when you are in good mood and not bothered about other things, gambling shouldn't be done with anxiety or even over excitement in other not to incur unexpected loss.
As you said, gambling should done without greed, it is advisable to gamble with what you can let go if you eventually become unlucky, most gambler forget the warning of casinos that said gamble responsibly, although they may not have explained it in details but it means gamble with caution, don't be excessively involved with what you can forfeit, for me I just think that gambling shouldnt add to anyones burden rather it should be an activity that people should engage with smallest amount of money to avoid regret.
But it is very difficult especially for people who have a very large winning experience, their greed is much greater until their brains work very irrationally about gambling.
Maybe those of us who can talk like now have gone through a difficult time with gambling where addiction and not wanting to stop playing causes a financial mess that in the end we realize that gambling should only be based on fun, no other goals, then there will not be any burden when gambling, such as frustration because they want to win and what happens is only defeat and defeat.
But it becomes very interesting when we are feeling addicted and then that day stop gambling for up to a month, you will find more peace.
