Attempting to write action, on the other hand, I find excruciating. I can't picture action scenes. I'm the same way with movies - in a long action sequence, I have to struggle to keep my focus. My mind just switches off.
Fortunately, there's no one correct way to write. ;-)
Action scenes are great in movies, in novels not quite as great. Action scenes are hard to write, partially because they are description on steroids. Take a sword-fighting scene. How much detail do you need? Do you consult a fencing expert, or just write a general description? Action is tough to write.
