How do we regulate our emotions while betting and how important is it?
Now, we can get to regulate and manage ourselves entirely to avoid them by tackling them for the reasons that caused them in the first place. As we know, overconfidence is caused by the emotion of being overbearing about ourselves and what we are capable of. This actually shows that we believe too much in ourselves. Since this is the cause, we can reverse it by moderating the way we think of ourselves. It will be easy for us to change it if we believe that we are not perfect and we can make mistakes and rather be neutral instead of being overconfident.
As for fear and anxiety, fear is more the cause of the issues in gambling than anxiety, it makes us abstain from gambling when we should gamble but pushes us to gamble when we should not. It also makes us reduce the risk we take when we should increase the risk, or increase the risk when we should reduce it. But for anxiety, it is a lesser evil in gambling and I believe it often happens in line with impatience when we are expecting the outcome of our gambling.
Lastly, there is one important point that you clearly omitted, and that is greed. I fear Greed and Fear in gambling as the main factors that cause the loss of gamblers. Greed often happens when we are not contented but want more. This is especially true when we are gaining but want more until our greed puts us in trouble. Above all, we should be disciplined in gambling, we should have a good approach towards it even as we have the best budgets and plans towards gambling.
