Greg,

In MTMII in the “How to use this book” section it says to “Work through Sections 1,2 and 3 every day to expand your limits.” Four sentences later it says “Limit your technical development sessions to no more than 30 minutes including rest, to stay mentally and physically fresh”. It’s not possible to get through all of those exercises in 30 minutes unless your just mindlessly playing through them. So would it be best just to do one of the keys in each section and then move on to music?
