Don't explain yourself to much. Sorcerers say that in every explanation there is a hidden apology. So, when you are explaining why you cannot do this or that, you're really apologizing for your shortcomings, hoping that whoever is listening to you will have the kindness to understand them.
Every one of us, young and old alike, is making figures in front of a mirror in one way or another. Tally what you know about people. Think of any human being on this earth, and you will know, without a shadow of a doubt, that no matter who they are, or what they think of themselves, or what they do, the result of their actions is always the same: senseless figures in front of a mirror.
