So he's saying you have to have OCD to get anywhere, because that's what collecting bus tickets, or spotting trains is. It's a disorder. Calling it a theory is quite a stretch. And tacking on a bunch of "things" the theory says, is just stabbing at the dark.

"An obsessive interest will even bring you luck, to the extent anything can." - how I'd categorise the entire article. Ironically it's also an accurate categorisation of one's involvement in the Y Combinator Seed project: "to the extent anything can".

Let's encourage everyone to develop OCD for things that matter. Good luck with that.
