I have to say what I do is not easy and there are definitely moments where I feel inadequate to the tasks I've set for myself. And that's hard to feel - like you're giving your life to something and you can't really do it as well as you want to do it.

The interests behind fracking are very powerful and they've managed to control the dialogue for a while, because they have forced people to sign disclosure agreements; people who have had negative experiences who are not able to speak out because they've signed disclosure agreements with the gas companies. Things like this. They've managed to strangle the opposing viewpoint, but it does seem like the people who are against fracking have started to gain some traction and the realities of what an environmental nightmare it is are starting to become known.

I try to use pain as fuel for my work.
