It is not the end of the physical body that should worry us. Rather our concern must be to live while we're alive - to release our inner selves from the spiritual death that comes with living behind a facade designed to conform to external definitions of who and what we are.
I'm constantly thinking about what I'll do next. I never count on music being a career of longevity. I mean longevity is key and I hope that it lasts but you just don't know because it's not in your hands you don't make the decision.
