These prints by Orange Beautiful give the best (un-sugar-coated) advice, don't you think? What it means to me: quit whining and complaining, and just do what you need to do. Simple as that. Because we all have a purpose on this earth, and it's our job to be responsible for discovering what it is and then following our own unique path.
So quit your belly aching and hop to it! (I'm talking to myself, but maybe I'm talking to you, too....? You decide.) :)
