When writer's block comes from not wanting to dive into the emotional world I'm trying to create... There is of course the voice that whispers, will they believe the superhero story you're trying to create? Actually, it doesn't matter that much, as I've seen watching Contact, a French TV series. I've changed the plot because my character was way too passive - much more interesting if she's driving the story; I've been able to do this by realising what does she really want, how SHE wants the world to see her when they know she has superpowers. Remember that you should write the story that YOU want to explore - at least while you're still learning to write.
