key to practical polymathy

I've long been interested in polymathy and written about it here and for Aeon magazine. I found though that the subject is both engaging and elusive, it sort of slips through your fingers. People like the concept of polymathy but then think 'what next'. Today i realised the thing holding people back is a fear of learning something new. For whatever reason. Often they have ceased to give themselves permission to learn something new (reasons being - too old, too busy, not talented etc). My breakthrough is Micromastery- because it- ABOVE ALL ELSE- restores the permission to be interested in whatever you want. It restores the permission to learn. Anyway after that trumpet burst I just want to remind the loyal readers out there the book is coming out in May courtesy of penguin books...
