Sport Polarisation is more than just prioritisation of your sport performance over other things. Prioritisation means varying degrees of priority, shades of grey. Polarisation is binary. There are no shades of agree, there are “1’s” and “0’s”
If you want to become elite, you need to polarise your life around your sport. The only things that are”1’s” in your life are the things you must do (school or work) and the sport you want to become elite at. Everything else is only added in after those two things are taken care of.
That’s what polarisation means. Read more about sports polarisation in The Sports Motivation Masterplan.
