My second life is that of a competitive collegiate rower waking at 4:30am so this all resonates very strongly with me. It's especially noticeable on campus where people will party hard and then sleep until 1pm when possible; you really come to appreciate the tranquility in the morning. Add in the rush of water moving by leaving ripples on the mirrored plane of the river and the sunrise over the city and you get a form of meditation most will never come to experience. I can't say the same as you in terms of my questionably existent social life, however.
