“After more than two thousand miles on the [Appalachian] trail, you can expect to undergo some personality changes. A heightened affinity for nature infiltrates your life. Greater inner peace. Enhanced self-esteem. A quiet confidence that if I could do that, I can do and should do whatever I really want to do. More appreciation for what you have and less desire to acquire what you don’t. A childlike zest for living life to the fullest. A refusal to be embarrassed about having fun. A renewed faith in the essential goodness of humankind. And a determination to repay others for the many kindnesses you have received.”
