"Back home I did whatever I happened to want at the time, unless I was doing something I had to do, like go to classes or make dinner or something like that, and those were never onerous enough to strain my mental resources, because I did not consider myself and my magic to be necessary apart from my general value as a person. I didn't even particularly bother to strengthen my magic apart from whatever exercises of it I happened to wish to do for their own sake, because I was going to be a Great Mage someday, and what did it matter if that day came later rather than sooner? Here not pushing myself has a cost measured in lives."
