Until I read "How to Fail at Almost Everything and Still Win Big" which makes the strongest argument I've seen for having a "talent stack" and combining skills that aren't typically combined. Each skill increases your odds and essentially this boils down to Good + Good > Excellent. You can leverage a combination of average skills to great effect.
The author describes himself as mediocre at art, decent at writing a joke and having business experience... not that noteworthy in and of themselves, but mixed together resulted in Dilbert.
I've occasionally speculated that in a world with 8 billion people, there exists a job/activity for which I am the absolutely best candidate, because of the perfect match of my very specific mix of skills and the very specific mix of skills required. The tricky bit is finding that match, I suppose :)
(1) Be best
(2) Be first
(3) Be the only person in a unique niche (a useful unique niche)
(2) & (3) are far easier than (1).
