An arrow can only be shot by pulling it backward. So when life is dragging you back with difficulties, it means that it's going to launch you into something great. So just focus, and keep aiming. My arrow tattoo next!
True as it's said. And to be honest, this is something we quite often forget. At least I do. At times it can feel as if whatever you're doing got easier. But do know that it is YOU that got better at doing it, and not the "thing" that got easier ;
