I've observed that high IQ people who tend to function well — certainly not a given — are extremely disciplined.

Basically as I see it, using every bit of rational intelligence to tame and condition the rest of their being (emotions, health, social, will, etc), develop all the other forms of intelligence.

The 'dark path' for most seems to be an ironic world view, which leads to a sarcastic mindset and ultimately nihilism if not contained. Hence a major lifelong requirement is to really learn what self-love means.

I have no idea what my IQ is, I just feel it's too much or too little for my own sake; case in point I finally stopped hating myself and learned self love at 34. Changed my life, like step 1 of a major transformation.

The only recommendation I'm certain helps everyone is Stoicism.
