I'm inspired by the following people:
Teachers and thinkersCarl Sagan - the man who gave me answers when my teachers were frightened of the questions. He was the greatest teacher I never had: he taught me how to think, not what to think. He's the reason why I studied science, as well as the reason why I became an atheist.
George Carlin - one of the greatest comedians of our age. Such a shame he's gone now.
Eleanor Roosevelt - one of the wisest women in history.
Winston Churchill - our greatest leader.
Mohandas Gandhi - peaceful resistance is an extremely powerful force.
Johnny Clegg - the White Zulu. This musician did a great deal to popularise Zulu culture in South Africa. His groups (Juluka / Savuka) helped bridge the gap between our nations.
Eratosthenes - worked out the circumference of the Earth, the tilt of the Earth's axis, and the distance between the Earth and the sun - amongst many other things. He did all this with the most primitive resources way back in 276BC. Despite his achievements, he was known to his friends as being the 'second-best' at everything. I'd love to know who came first!
Trans PeopleLando - Seeing him on Maury made me reconsider FtM transition. I'd decided many years ago not to transition because the results didn't seem convincing. But if my transition is even half as good as Lando's I'll be very pleased with the results.
Caroline Cossey - she was the first trans person I'd ever heard of. Reading her story made me realise what was 'wrong' with me. I owe her a lifelong debt of gratitude for helping me understand myself.
KingGutterFace - a controversial choice, but he's clearly been through a lot of hardship in his life and it has built his character. I admire him for surviving and becoming a strong individual.
My friends at Susan's - every single one of us is brave enough to do whatever we need to do to feel comfortable with our gender identities; that's why we're here. I salute you all!
Fictional PeopleX-Men - I was a huge fan of the X-Men growing up. I always felt like a bit of mutant who was hated & feared by those around me. The X-Men made me think it was OK to be different and that there are other people who go through the same thing. It's just a shame that I can't shoot laser beams out of my eyeballs too.

Star Trek - I love the humanist ethos that is central to the Star Trek mythos. I love the fact that their future is about peaceful exploration and self-improvement whilst being humane to each other. I also love their acceptance of a wide variety of people. Infinite Diversity in Infinite Combination.
