yeah intelligence is so dependent on the criteria of how it is to be measured.

Intelligence doesn't seem to be shit unless it's utilized. And, then, exactly HOW it is to be utilized is only relevant to the person trying to accomplish a goal and other incalculable variables.

It's better to not even think about it at all and just do the best you can or whatever you're comfortable at doing. Happiness should not be a goal; it should be the experiences you have. I don't really know.
