It's essential that we understand that taking care of the planet will be done as we take care of ourselves. You know that you can't really make much of a difference in things until you change yourself.
I think writing really helps you heal yourself. I think if you write long enough, you will be a healthy person. That is, if you write what you need to write, as opposed to what will make money, or what will make fame.
It's an awful feeling to write something that you feel is really important... and to feel that you're being published by people who really don't get it and/or don't really care.
