Sometimes you just got to believe that for some reason things always do eventually turn out for the best.
Give it time.
At first you try and control everything to go in a way that you think you know it should. And when it doesn't you lose faith in things, in people and in yourself. You feel defeated, rejected and like a loser. And that is a terrible place to be in.
I reckon there are times you can do your part, and if it doesn't turn out the way you want then let it be. Let go of control, of expectations, and just believe in God and the universe to lead it to what it should be for the good of all. This doesn't mean giving up or being weak, on the contrary it just means you know when to shift your focus and energy on things that will benefit you.
Life is way too precious to dwell on things you can't control. Everything is in your mind, you change your perception of things if that allows you some peace. We all could do with some peace.
