How do you know what you know? Think of all the lessons that you have had to learn the hard way. Consider the great price that you have had to pay in terms of struggle and sacrifice in your life so far. Dwell, just for a moment, on why you have clear, actual experience in areas of life that others can only dream and theorise about. Then allow yourself to feel proud of all that unique experience. Then you start to see how you can really make it start paying for itself at last, in all kinds of unexpected ways.
