Here is a very good example for Knowledge. This pencil can be used only if it is Sharpened - everytime when it becomes Blunt, or else we ourself feels irritated. A simple Pencil itself needs to be sharpened everytime, but Why don't we think that our Mind as well needed to be refreshed as time moves on... If we don't do so, others would be irritated by our attitude. "Why I say attitude is that - Lack of knowledge would finally hit Attitude".
So Sharp the Pencil daily by Sharpening them, and simultaneously Lets sharpen our Brain by updating day to day's News & General Knowledge. . .
