This last point is so important it should almost be mandatory: If possible, spend time in nature. If you live in a city where nature is hard to find, research botanical gardens, greenhouses and Zen gardens in your area. Take long walks in the woods, on the beach, whatever landscape calls you. This will provide your body and mind an opportunity to relax and help to establish a deeper connection to yourself, outside the noise and movement of life. All of which is vital to setting your intentions and all aspects of preparation.
