The common eye sees only the outside of things, and judges by that, but the seeing eye pierces through and reads the heart and the soul, finding there capacities which the outside didn't indicate or promise, and which the other kind of eye couldn't detect.
Mark TwainA jackass has that kind of strength, and puts it to a useful purpose, and is valuable to the world because he is a jackass; but anobleman is not valuable because he is a jackass. It is a mixture that is always ineffectual, and should never have been attempted in the first place. And yet, once you start a mistake, the trouble is done and you never know what is going to come of it.
Mark TwainYou can't no more teach what you ain't learned than you can come from where you ain't been.
Mark Twain
