Ok so when I asked my old supervisor for a b-school recommendation, he asked me to just write it out myself and that he would read it and make any necessary changes before submitting it. I'm at the dreaded part that asks about my three biggest weaknesses and am at a loss. Whenever I've been asked this about myself in the past, I've always used the whole spin the weakness into a positive tactic (i.e. "I can be a bit of a perfectionist"). But how would I do this from his standpoint - "Kati worked too hard?" I am stumped.
