When failure knocks at your door, you have to greet it, invite it in, make it feel comfortable, and eventually ask it to move in. Failure needs to be absorbed, somehow, in order for the learnings to become a part of you, to make you better, to prevent it from happening again.
If you deny failure, on the other hand, it will not simply go away. Soon enough it will spread, and your problem will become a problem for the neighbors, for the neighborhood, for the culture, for the village. It will transform into an existential threat. It will just be everywhere, always noticeable, never hidden, a memento of your own incapacity to accept.
Failure is not the end of the world. Pretending not to see it might just be it.
