What's cleverness ?

I am called seedha sadha in my family. I feel offended when they say that becoz in today's world simple people become prey to clever people.
Hard fact but true.

Analyzing myself I think i am smart person but not clever. Reason is I don't know what's cleverness and how does one become clever.

So what do you think is cleverness, chalaak or shatir lomdi ??
Is fooling others makes one clever ? Or getting laid with multiple women, having multiple gf/ bfs, lying to people around you, Will you call such person clever ??

If not him, is a ranker in school or college who is  very strong in academic. Is he clever ?

What does anyone do which makes them clever ??
It tickles the mind isn't it, you are able to judge a person clever or dum through your experience with them but its difficult to actually define cleverness.

After storming myself again and again What I came to the conclusion that the one whom I'll call clever is who is able to get everything out of the other person and they don't know about it. he is a person who has skeptical mind. He'll be able to introspect and take whatever he needs from you for himself without you realizing it. Like deligating a useless work but making it sound like its a hell lot important job and you have been shouldered a big responsibility, a trick to get work properly done by juniors. Now what should one call this cleverness or smartness?

Normally what I have noticed is clever word is used in bit negative sense. You call a scholar, person with good convincing power, leadership skills smart and not clever.
Manmohan Singh is smart but Sonia Gandhi is clever.

If you notice the trademarks of both the words are same. A clever person is also smart but there is a mean, motive or gain in their actions.
If smartness is a talent then cleverness is how to you it. You can be taught how to become smart but not clever that is something that you learn with time and bad experience. I call it bad becoz you will be the cry first and then you will learn through that fall.

I would say In our world its better to be clever than just smart.

Different people have different thinking not many will agree to what I have said that's becoz we all have lived a different life and have different experiences. What might be bad for you might not be for me or what might not be good for you might be for me.
So we all have our own school of thoughts. I would like to know what you think and what is your understanding.
