Inspiration or Execution?

What is your writing gift? Hopefully you have both inspiration and execution, but are you especially skilled in either one? I have a couple of friends who are always coming up with story ideas--practically a book a minute. However, only one of them really gets down and dirty and writes things down. Personally, I am less likely to have that kind of "plotline epiphany," but more likely to actually sit down and write it when I do. 

How about you?
