Gathering the flotsam of newsprint around home and office to consign to the 'green box', I inevitably re-read some of the pieces in the newspapers that made me stop and think over the last two weeks or so.
John Inverdale's column about Andy Murray's victory over Lleyton Hewitt in the ATP tour was one.
He builds on the insight Murray's mother gave in an interview on how Andy evaluated Hewitt's game, and decided on his winning tactics five years ago, aged 13, watching Hewitt on TV rather than doing chemistry homework.
It asks the big question:
Can you actually teach that kind of innate ability to read and understand a game, or does it come somehow, somewhere from within. Can you teach that kind of focus? That kind of desire. That inner belief that one day you will - not might - be on the other side of the court to Hewitt, teeing off with Woods, lining up alongside Lampard, be next out of the gates after Bode Miller. Maybe you can't. Maybe that's what makes Murray exceptional. But maybe you can.
There are lots of parallels drawn between sport and business.But can any successful entrepreneurs say their ambtion was ignited and business strategy determined whilst watching TV rather than doing their homework?
Whatever, I've fended off passionate appeals by my children to subscribe to Sky Sports because I'm convinced they will mutate into a couch potatoes. Maybe I shouldn't be so circumspect.
