I’m also thinking about the relationship you have with yourself, and how all of the parts of you, past, present and future interplay with each other and the world around you. Which is a long-winded way of saying I want to help you have the relationship you want with yourself and with others. I want you to find happiness, joy and health. I'd like to help you identify and meet your goals, and I am a warm, supportive presence whether or not you have any idea as to what your goals might be.
