Me either, I don't like when I am losing. But we can always hide in that reasoning that we're learning something new just to justify and flee from that disappointing moment.
Actually, I want to say here that this is not only your case, but also the same in my case and I also believe that there are many more people here who feel this way when they lose while gambling and at the same time the next expression is also the same.
That doesn't happen to all of us but we have to enjoy still even if we're on the losing side and we can move on from that.
Accepting the reality that sometimes we win and many times we'll lose is hard but, you'll get used to it.
Actually, it would be wrong to say that it doesn't happen to all of us. Because I think most people in gambling even though their total loss amount will be much higher, they still win in some cases. Personally, I think no one has worse luck than me because I face losses most of the time, but even then, the occasional win that comes through gives me the motivation to move forward.
