I don't want to follow the approach of conquest of the earth -- build bigger houses, bigger roads, fly in airplanes all the time, own many cars. Nor do I want to live in the wilderness, with no shelter or clothing other than what I find in the woods. What I want to do is to work with nature, to create the life that I want in a way that respects nature. For example, in gardening, we work with the laws of nature to coax the growth of the plants we wish to cultivate.
With my health, the conquest approach would be to fill myself with caffeine and medications, to try to keep going regardless of what may be happening in my body. The wilderness approach would be to let sickness run wild. Neither is what I want. I want to work with nature to make my health what I want it to be. I want to give my body the rest, exercise, and nutrients which best suit it, just as I try to give my garden crops the soil, water, and sunlight which best suit them. When sick, I want to do things that will drive away the illness. I want to work with nature to grow my health.
In figuring out what to do with my life, I have to realize that it's not realistic to do everything I dream of. My aspirations are many times larger than my time and energy. I also have to accept that I have a certain temperament and certain abilities. There are some things that would be cool to do, but they just aren't for me to do. But that does not mean I am just stuck with who I am right now. I can learn new skills. I respect the nature of who I am, but within that, I can shape my life to what I want it to be, just as within the laws of nature, I shape my garden and my health.
