Portraits of my Heroes: redux.

I'm trying to decide who to draw next for my "Portraits of my Heroes" series. It's difficult. Really, who can I honestly call one of my heroes? Douglas Adams was the easy one to decide about. After all, I just finished reading The Salmon of Doubt for the nth time. While I was reading it, I felt at times awe, at times completely uplifted. When I read the bits that other people had written, I felt an intense amount of sadness. Nearly seven years since he died, and it still feels acute. It makes no rational sense. I never even knew Douglas Adams, just read what he wrote. I'm thinking, then, that I have a workable criterion for choosing my heroes. I need to sort out whose work lifts me up, inspires me, makes me cry, makes me vow to improve the world. I need to sort out who I can't imagine a world without. I'm afraid it might not be a very big series. But everyone in it will be vitally important.
