This first one is that you know nothing about someone just by their outward appearance. It should never just by anyone of characters. For instance, if you look at a good looking person, you can only see their skin color, physical tilt and maybe fashion. But above beyond that you can't slowly make up your mind on their output appearance. But if the good looking person turned out to be horrible in nature but if they take any serious talent or skill does you see how outward appearance can be misleading?
