Yes, some games involve luck but if choose the wrong game it can still be a losing game, and the wrong gambling platform even when have the best luck in the world. Therefore, there are a lot of things that need to be put into consideration as a gambler if wants to thrive in the system.
If I was the one that lost the game, I also consider it not to be my day. However, I always consider looking into the things I may doing in the wrong way, and things that need correction.
What the OP said is actually a reality that often happens to every gambler, every time we lose of course we will try to find excuses with say unluckiness, while when we win, many people are proud and say that it is the result of analysis and also hard work without seeing any luck factors If I was the one that lost the game, I also consider it not to be my day. However, I always consider looking into the things I may doing in the wrong way, and things that need correction.
.What you said I fully agree, because if we lose should not continue to blame fate, but instead we must think logically to reflect on themselves and also dig deeper into the causes of the defeat, so that by understanding and finding the key to the defeat, of course we can get a solution to be able to increase the chances of winning in we next bet or gambling.
