That's right, it is very important that we be able to guard ourselves so as not to be incited by greed which can cause us to experience greater losses when we follow the desires of greed. It's possible that those who play the game impatiently will of course not be able to control themselves and if that's the case, it's likely that they will take actions that are not carefully considered, in other words they will take action spontaneously without thinking about the impact that will occur. what would it be like if they did that? and as you said, if they are impatient, it is likely that they will only experience defeat.
I once saw a gentleman who was standing watching the progress of gambling, he continued to pay attention and observe the progress of gambling with his hands folded crosswise in front. and immediately he placed a bet and was able to win, I don't know what he was thinking while he was watching and observing the gambling but what he did made me a little confused. Maybe this is one of the behaviors called patience in gambling, so that you don't place bets carelessly and just hope for a miracle.
By experienced for sure, the person you mentioned knew that there's always a good timing for everything and he use that knowledge to assess and analyze before placing his bet, though it's not always the outcome as knowing the nature of gambling, even how sure you are there's always upset that can take place,
you just need to be ready in accepting whatever the outcome might be, it helps you not to engage that much and lose more if ever your prediction or your analysis did not work according to your plan.
Keep it in mind that re-assessment will always gives you better insight instead of blindly place another bet in hope that it will allow you to recover your losses.
What you say is correct, there is no harm in observing and analyzing the gambling we do, but of course we have to be prepared for whatever the outcome is, especially with losses that are certain to occur. there is nothing that can make that defeat not happen. all gambling and everyone who gambles will definitely experience defeat, even though they are experienced or gamble using a strategy that they think is accurate to be able to win, but defeat will still occur. What we have to pay attention to is our attitude in dealing with gambling. If you lose, it's best not to think too much about it because that won't change the situation. In my opinion, accepting defeat well and walking away from gambling is what you have to do.
Sometimes there are gamblers who have lost but want to turn things around so they think "maybe in the next gambling game I will get a win that can turn things around" they hope that luck will come to them, whereas luck cannot be expected to happen as desired, luck will happen with itself. Don't think about being able to reverse the situation, in my opinion it will only make things worse. You have to be patient when gambling, because when the time comes, luck is on your side, then winning cannot be avoided.
