None of this is really true. This is a horrible platitude. What matters is that you are valuable to those around you. In the wider world most of us are not worth much. There is always someone that's more of those things than you are, and you are not unique either. Its important to realise that and accept it and go on a journey to better yourself, instead of deceiving yourself into thinking you are great just the way you are. You are acceptable, but we all can do a little better, try a little harder, learn a little more, be a little more humane. Think about it.
