When I'm not engrossed in someone or some concept I take deep enjoyment in less abstract things. I have a great love for music, and like to enjoy nature frequently.
Some of my favorite moments in life are when I can take something and finally see the principles and structures at it's core, the network diagram that represents a web of economics relationships, or the algorithm that determines the growth pattern of a tree.
On the other hand, some of my other favorite moments in life are when that kind of clear analytical understanding of a thing are totally out of my grasp. Listening to a song for the 12th time in a row because it's that amazing, sitting on a quiet mountaintop hearing the wind and little else, or simply being with those you love.
