The joy of been smart cannot be over emphasize because when you are smart in whatever you do people tend work because the goal in every work is not just be hard working but is to be smart because smart work is better than hard at all time.
In most work and office area people are not really care of whether are very hard working but they care more whether you can handle pressure that may arise during work, note that when pressure arise in any work your boss and other around are not too much interested in your hard working spirit but they will be looking how smart and logic you are to handle situations that may arise from your day to day activities.
I tell you that they are people who are looking for your smartness in whatever you do which will make people to admire you at all time.
There is happiness in ever persons who are aware that people talking positive about because of their smartness, so we should not be only care in doing our personal stuff but we should be smart logically to handle situations that comes our way.
So every one of should by all means learn how to be smart in whatever we do so that can perform optimally in whatever we do.
The truth of the matter is that everyone wanted to feel safe is whatever they do and the situation were people start talking good about you because of your work and smartness I believe that we have emotion and feel happy whenever we are praise for doing some particular stuffs.
