i agree with everyone here who says its not necessary smart ppl are happy or dumb ppl are unhappy or vice versa. even the smartest ppl cant make the worst decisions of their lives.. but i must say smart ppl have an edge, they are aware of their surrondings, they know how to react or respond to ppl and situations... they are alert.
Yes, you are right smart people are better aware of their surroundings and also education gives them a big lead. I agree that sometimes some irrational decisions can be made but mistakes are made by everyone. No one is perfect, this is why we learn from our mistakes, sometimes the illeterate people do not, this is where us people who know how to think and have education with us have an edge.
you know what... you dont need to be very literate do take good decisions.. There is a natural built-in analysis and problem solving skills inside human brain and not much people have that.
I agree, but see those people who are successful but they are not educated they always have that nudging feeling that they are not educated. When you are a businessman and the rest are educated and can speak better english than you and write better than you plus converse better than you with other people you will automatically feel it and no matter how successful you are or how much money you have this feeling rarely goes away. Also this lack of education almost always comes up in the kind of personality you have.
