This weekend, reflect on whomever/whatever you invest time, effort and energy into. Are you in a situation where the give-and-take is fair and mutually satisfying? The key word here is “mutual”: if there’s an imbalance, either it gets fixed or you’re better off moving on. Don’t stay where you’re not appreciated; if you haven’t been pulling your weight, it’s time to start. You deserve fair treatment – and so does everyone else.
