Simply because gambling is not a way to make money. If you believe in luck, then believe that luck plays with us as it pleases. If everything were so simple that you could write a dissertation on casino games, then half the world would not be poor. I always look at casino games as entertainment for which I must earn money. That is, I bring to the casino funds that are earned by labor, and here comes some reward. You should neither be greedy nor go crazy; otherwise, everything ends badly. Simply an easy attitude. And also the thought that it is not scary to be confident but it is scary to be overconfident always helps me to act correctly.
