Someone wise (probably my grandma, she was full of grandmotherly sayings) used to say that whatever happens, happens for the best. After many years of trial and error, I completely agree. Admittedly shit happens and it happens far more frequently than most of us would like it to happen, but even shit happens for a reason and you're better off for it, in some way or the other, even if you don't realize it at that very moment.
