The measuring of intelligence by academic testing is flawed. It can only reveal the ability of a person to absorb data. It does not test ‘life’ issues.
It does not test ‘outside the box’ thinking, it does not in any way imply or predict life success.
Success is not just gaining that job or accumulating that money.
In relation to money, the standard ‘3rd Generation’ seems ordained.
This is, the 1st Generation works their way up from nothing, and becomes a millionaire. The 2nd Generation, which might have worked with the 1st to gain success, or been merely the recipient, rarely increases or preserves that wealth. The 3rd Generation often loses that wealth. This is due to their inability to comprehend what is evident to those who were not born to wealth.
