Not very often, but when I do; it's for good reason... it's usually because there was something that wasn't meant for me anyway, so why stress over it?
A lot of people wonder why I don't really have any deep rooted emotions when something doesn't go my way... yes, they are very much there, but there's almost a sense of relief when something you've been questioning doesn't really work out the way you want to. I said it earlier in the week: life has a way of answering certain questions before you even ask them.
I truly do find the beauty in failure because without it, how can we honestly see what positive things are? So in short, I thank them all for showing their true intent. If I were a religious person, I'd fall to my knees and thank a higher being for showing me the light.
But since I'm REALLY not, I'll say it like this:
Thank them all: all of the mistakes, all of the "no" answers and all of the failures you've ever had in you life.... for being the best thing you never had. ♥
