Wow, is this ever true. Good motto to help you just let go and live and whatever happens happens. I try to always believe if it's meant to be, it will be. But my control normally screws that up. I always wish to understand more than some things allow.
Sometimes you just need to remind yourself that you can only do your best and if you're not happy doing what you're doing than you need to remind yourself why you're here, what you're doing and where you want to me. And then make a change. And act on it.
