I have lots of ways to manage my stress, but one way I particularly love is to sit back with some beautiful, relaxing music playing in the background, close my eyes, and picture myself in a beautiful, serene place that is special to me. It may be a pristine white beach, a lush meadow with birds singing, or the top of a mountain with an amazing view. Just spending a minute or two in this beautiful place I've created in my mind's eye helps me to release my worries and center myself. When I open my eyes I have more energy and feel great!
Hope this helps.
