I've tried everything, reducing caffeine intake, daily exercise, stretching, good nutrition, etc. We all need a physical, mental, and spiritual shot in the arm to keep us going. One of my favorite ways to get this boost is to go day-hiking.
Many people confuse walking with day-hiking.
In the last 15 years walking as a form of exercise has exploded in popularity, and I think it's great. But the big difference between walking and day hiking is that when day-hiking you remove yourself from your everyday life pattern. After a short adjustment period your body and mind begin to change. Somehow your problems don't seem as big, you've forgotten about all those chores you should be doing and you start to enjoy the moment. This is the magic of day-hiking.
