Energy comes from a body in motion, not a body at rest. So, to create energy, just do something. Anything really-it doesn't have to be brilliant or perfect. It just has to be activity that is directed towards the outcome you are seeking. For instance, if you want more business in the door, pick up the phone and ring someone.
Energy is most effective when it's focussed, of course, and it feels best when it's positive.
Skill can be easily developed by acquiring new, how-to information and then doing some practice. Information doesn't actually become knowledge until we use it and discover the effects. But I do know that when I apply it, miracles happen. For me it means making small commitments and requiring myself to keep them. Keeping commitments to others is not an issue-it's essential.
