One marker that I’m seeing someone clearly is when I understand how their strengths are also their weaknesses, how their genius lives right next to their dysfunction. I know that I’m further away from clarity when I am overly excited or overly skeptical.
In fact, people with extreme traits can often structure their lives in such a way that they can trade on the ways they’re exceptional, leaving no persistent reason to address some particular deficit they have. And, generally, people are savvy enough to hide their dysfunction. People will disappoint you, eventually.
The superheroes you have in your mind are nearly all walking flaws who’ve maximized 1 or 2 strengths. Humans are imperfect creatures. You don’t “succeed” because you have no weaknesses; you succeed because you find your unique strengths and focus on developing habits around them.
