Human groups

The mankind can be segmented into four groups:

1. Not-knowing people, not knowing that they not know. Those people are 'retarted'.

2. Not-knowing people, knowing that they not know. Those peole know their limits in which they can operate and are appreciated by the rest.

3. Knowing people, not-knowing that they know. Those people are asleep, just wake them up.

4. Knowing people, knowing that they know. Those are the 'teachers', the smarter people, whom we can listen to.
