The question is whether it takes natural talent or perseverance (also called grit) to accomplish great (or good) things. Did Einstein figure out relativity because he was really smart, or because he had uncommon grit? This talk implies that the latter is often more important in achieving lofty goals.
The problem is that sometimes someone with grit will continue to pursue things that s/he may not be able to complete. It turns out that grit and stubbornness may be two sides of the same coin, and when you are in the middle of something, it may not be possible for you to figure out which side of the coin you are on.
