Sometimes it takes falling apart to see exactly how or what loosened the mortar. Sometimes we find we are responsible for the how & the what. As unpleasant as it is when it happens, one cannot help but appreciate these times for what you learn serves as a beacon. Of course this is only half the battle. Which means you're already half way there.

It's my opinion, with some people, just knowing they are alone, living inside of their own miserable, self hating, dysfunctional mind, with their own immature, insecure, self pitying self is its own revenge. Their existence is their karma.
