He makes a good point - sometimes it's that last little bit of skill that makes the difference between a success and a failure. When you completely master something, the whole game can change. The problem is that it's insanely hard to completely master something - there's the time involved in doing it, but there's ALSO the fact that you're competing with everyone else who's also trying to master it. The real value of the 80/20 rule, I think, is that it gives you the ability to devote time to several different pursuits, giving you a combination of skills that few other people can match. Call this the 'Scott Adams Rule' of success - you can either be the very best at something, or be in the top 25% of 2 or more things and combine them.
