Can't think off the top of my head any quotes that I didn't previously understand. However: I really like your quote "We often teach best what we need to learn most". I can very much relate to that. It seems so much easier to help someone with their problem than to help yourself with your own. There is actually a quote for that..not entirely sure how it goes, but something along the lines of "I want to be known as the person who could help someone else even though I couldn't help myself".
