3. Knowledge is power
Every smart person will agree with the fact that knowledge is indeed power. The more you know, the better you will and the better you perform in your work. You will always strive to gather information based on everything and anything. You will try to keep updated about recent events so that you can always participate in any conversation or at least not come out as an ignorant fool who has no idea about the world. You will also feel a sense of satisfaction when you are able to use some prior knowledge to use.
