I think if you really feel the need to change the world, you're going to have to go down that road. But you don't need to change the world to make a difference. By being honest, you can save a few people out there worth saving, starting with yourself.
Saving yourself is a good start. That's what I'm doing right now. Today I started writing my letter of disassociation, six pages long. It's still weird that I'm doing this, feels somewhat unreal, but I won't back down or go back. It'll cost me greatly though, I don't have close friendships with JWs anymore, but was raised by a Single Mom, so our relationship is pretty close. I know that she'll hurt badly and being the typical mindless follower she'll end up shunning me, because she thinks she must do so.
