A failure should not be the end of the situation.

Following each failure, it is worth performing an introspection to determine just what went wrong.

You may want to "play" through the incidents, step by step, in order to determine when things stopped going your way. At that point, you may consider alternative scenarios.

In this way, your failures can be learning episodes, and your abilities and skills will grow with each failure. That does not necessarily mean that you will look forward to the next failure, but you will certainly be able to squeeze some benefit from it.
