I've been meditating on the nature of failure lately, as I have had my good share.
What causes failure?
Personally, I've learnt that it is my stubborn-mindedness and courageous defiance in the face of overwhelming facts. Ironically, these two same qualities are drivers of my success. I push my Self to a brink, then either fly or fall.
Most people don't want to live like this, but since my own brush with death at an early age, I've lived recklessly and wildly, carrying a deep-hearted death wish glossed over by verve.
