You are always* the reason for losing, not only in a streak. But you are also always* the reason for winning.

I know in our culture, by default, losing sucks. But this is exactly it, it’s our culture that is what lets it suck.

It is just as well possible to imagine a culture where losing is seen as a sign of strength. Where each loss is celebrated. Where loss does not mean failure, but an additional data point of experience for your quest to self-improvement. In that sense, winning or losing would not matter, because you are always succeeding at getting more experience.

This culture does not have to be imagination. There are people on Earth right now who are truly living it. You can join them right now, if you want to. You just** have to change your point of view.

If you want/need additional words: games are supposed to be like this. That is basically the definition of a game in a biological sense: organisms in our world play to build skills for the real situation later in real life. Dota 2 is a game. It teaches you attention, hand-eye coordination, teamwork, and a plethora of other things. Wins or losses have no consequences at all (except in your mind). Look at any nature documentary: in any of the massive amount of animal species that you see play, does the “loser” of one of such games look particularly “defeated”? No, they always continue on as if nothing happened. Because nothing did, or rather, only positive things, one more set of experiences.

*: “always” in a statistical sense of the word, not literally always

**: this is incredibly hard, don’t beat yourself up if you can’t immediately do it
