Just in case, what amount will be looking like a nice hit for you to leave a casino just immediately for maybe your first, second or third hit on the machine as you have just walked in?
Anything above 200% of what what I came in with (aka my planned gambling funds for the day) is good enough to take home. I feel like there is no point in trying to push your luck. If you get too cocky then you definitely will lose all your money, eventually, if you keep on gambling. That is just how probability works.
Although you lose money in the long term, as well.
But that does not matter to me because I do not see gambling as an income source. Frankly doing so would be very dangerous and could lead to gambling addiction very easily. People underestimate this.
