The Importance of Understanding Mathematics the Second Time

I have tremendous sympathy for people who don't understand mathematics. I still remember very vividly the days when I knew no mathematics at all and I was functioning as a human being. It's possible to be very intelligent, hard-working and sensitive while being stupid at mathematics that's perfectly possible. If you are worried about taking an exam or something or having to understand something on the spot then let it be the second time just prepares of that they say.
