A quote often attributed to Woody Allen: 90 percent of success is simply showing up.
Sure, that can be read in the Malcolm Gladwell sense, putting in one's due diligence over the course of time, but it can also be read as, well, simply showing up. (Please try to resist the urge to speculate upon my preferred reading of that quote.) Insofar as our inability to reliability measure and assess "intelligence" in any truly meaningful sense, we also cannot wholly discount the role that perceptions play in the assessment of intelligence. I mean, show up enough to become a regular commentator on Fox news, and you'll have nearly 100 million people thinking you're a freakin' genius.
Expanding upon this a bit, and broadening our definitions of intelligence:
The Beatles certainly put in their 10 thousand hours--well, Paul, John and George did. Ringo, however, did not. Ringo never practiced and he didn't even keep a kit in his own home. Moreover, he's left-handed but set his kit up in right-handed fashion; consequently, he couldn't do a proper roll even. He, pretty much, just
showed up. And
yet... Ringo is a freakin' genius, and he's widely respected even by highly proficient, virtuoso type drummers.
Phil Collins is perhaps the drummer most stylistically similar to Ringo, and yet, I think most would agree that
he is of the "highly proficient, virtuoso" variety. Compare the drumming (isolated, with bass) on the Beatles' "A Day in the Life" to that of the latter section (also, mostly isolated bass and drums) of Genesis' "Cinema Show"--from about 5:50 onwards--which Phil claims to be directly inspired by "A Day in the Life":
Then there's Angus Maclise to consider, and even Mo Tucker, but I'll leave it at that.
