If you must gamble, do it moderately and if you must continue don't forget to take profits. That's the main part many people forget, you can't be gambling and be anticipating profits later, do it in any way you can to maximize your profits otherwise gambling isn't for you
Not much have been made from gambling but just pure fun. Gambling with the intention of winning big is sometimes detrimental to the success of some gambler. I am not saying we shouldn't be ambitious when gambling but I'm suggesting that we should be take a subtle approach towards gambling with the aim of making fun out of it. Gambling took many dimensions some of which included people who took competitions in gambling thereby staking high amount of money to either win or lose. For me, it has been more of a fun thing and I don't do gambling with much ambition.
That way, your well-being and nerves will be preserved. I admire your position on it. Really.
