A lifelong skill, not simply in gambling. How many of us always restrict our passions and desires? The challenge is to enjoy gambling like a fine wine - moderately and knowing when to quit. What about losses? Not just financial, but emotional and psychological. Shouldn't we prepare for and accept them as part of the game? Controlling expectations and imposing limits. Doing so lets us enjoy gambling while understanding its nature. Isn't that a greener way to explore this glittering world?
I think how many people (gamblers) are able to limit their lust and desires is almost unknown, but I personally think most of them will probably do it for the safety of their gambling involvement, I'm not saying it has happened because it still takes the form of a plan. which they can violate at any time, and as an example let's narrow it down, out of 100 people who plan their boundaries of lust and desire when they have entered and are directly involved in the session then maybe I would say that only 30 people are still firm in planning their boundaries, and the rest they violate. I would say that the 70 people above don't seem to come to enjoy but are more inclined to exploit or abuse gambling by carrying the wrong mindset so that the impact is that they are trapped in a labyrinth full of disaster and adversity because they cannot be firm in implementing their plans because they are tempted by something that getting involved is tempting even though it's just a trap to get deeper.
Understanding is the main thing that must be paid attention to before they decide something, as you said that we must be ready to accept defeat and that doesn't mean we are ready to just win, I would say you are a coward and irresponsible if you only want to win but don't want to lose. Controlling expectations and limiting them will be very useful to stay safe..
