I am free, no matter what rules surround me. If I find them tolerable, I tolerate them; if I find them too obnoxious, I break them. I am free because I know that I alone am morally responsible for everything I do.
The coolest thing for me is the experience of floating and not feeling my weight. And hanging by a window just after sunset and watching the stars in the big black dome of the sky as the earth moves underneath.
