If you play any games involving chance (all or partial), your losses aren’t because of your effort, but because the system is designed that way, to give random results. So why do you feel down when you know that the possibility of losses is there, that no matter what you do, you’ll be just as good as any other players? Make sure that you come to play with such a mindset, that you’ll just be wasting money for fun, and no losses will be bad for your mental health.
