“Excellence in any field depends largely on three basic factors: (a) how well you know where you want to go, (b) how much you really want to get there, and (c) how strongly you believe in your ability to arrive at your desired destination.
Your performance is largely a function of your expectations for yourself. If you treat yourself as if you have something to offer, as if you have a contribution to make, as if you have a lot of potential, then you will behave accordingly. If you treat yourself as if you have little or nothing to offer, then this will likewise be reflected in your performance. Don’t sell yourself short! You have a whole lot more to offer than most people recognise. How can I say that? I don’t even know you, right? Well, if you are anything like other members of the human species who I have encountered, you will have all kinds of untapped potential…”
