HI Alan,
In answer to your question, my vision has changed over the many years. However, my purpose has only clarified with time and my values have solidified. Those are the drivers out of which my vision emerges. So I would keep your purpose front and center and then give yourself time to reflect, explore and tune into your intuition so that your vision can surface. And it will change or come more clearly into focus as you continue on your journey. Enjoy the ride!
Thanks for stopping by to comment, Alan!
