Let go of the details today: you have to face the fact that not every single one of them is going to line up nicely and neatly for you. But the good news is, your overall plan will work out quite well. It won't be perfect, but what is? You have to let go of that ideal: it will only stress you out and make you miss out on the chance to feel proud of yourself. You'll get a lot more accomplished if you just accept things the way they are and start working with what you have.
