Haha, wow. That's actually an awesome question on a lot of levels. I'd be impressed if someone asked me that. That's something that makes you think, and the answer is very telling. Nice one!
I'd love to be able to say that I honestly fail all the time, and more often than not it's my own fault completely. And I'd love for that to not be a death nail in a job interview.
Make it more human, you know.
Congratulations, you're hired.
