Fran, I've always loved your candidness -- this was one of my favorite videos you've done so far. What you said at the end is spot-on -- there's a lot of evidence to suggest that struggling with a task (and eventually succeeding) is far more rewarding, stimulating, and healthy than working on projects you know you can do. We like to think of scientists and engineers as people sitting around, pulling great ideas out of the sky, and moving on. But real research and innovation takes a ton of work; as you said in this video, if it comes easy to you, it's probably trivially unoriginal, or you just got extremely lucky. Effort is everything!
