When the rest of the household wakes at 4 a.m. there’s every chance that you don’t get done what you usually do first thing in the morning.
My old mum and my 7-yr-old daughter each reserved one of my ears. I couldn’t concentrate. But in spite of it all, I did manage to collect another 25 Harry Potter sentences.
First, I listen and highlight. Second, I go over those highlighted sentences and cut and paste those that are shorter than one line and that I can get to grips with more-or-less instantly.
Anything else is just icing on the cake.
