how did you make this transition?

i still, deep down, identify as being "smart". i don't like being wrong, and it's my go-to ego lick at work, "well bad thing x may have happened, but at least I'm still valued for being smart". it was my label in high school that i've never quite shed.

obviously now i have so many more facets - father, husband, leader, writer/reader. Smartness is just raw horsepower, it's what you do with it that matters. And there's lots of kinds of "smarts". As an example, my wife wasn't the traditional "book smart" but she's emotionally & street smart - knows how to get things done, how to think on her feet, etc.

but still despite that increased richness from life experience, I'm still "smart" and hold on to it

In what way are you smart? I started to think about the things I was good and bad at, and I realized I'm only good at certain types of problems and work due to practice and study. Try to be confident in your interests and pursuits where you know you have experience or you want to gain experience, but don't be overconfident and begin think you know about things that you barely scratched the surface of. A good start is to never assume you know how to solve a problem that has been unsolved for ages, in general. Often, the people who hang out here don't know that line because they think they're "smart".

My process was a multi-year process of recognizing my vulnerabilities. A couple of things that come to mind.

Meeting and liking people who were really different from me, with mindsets completely different. The kind of people I would previously judge as "dumb" were suddenly teaching things that improved my life. For example, my beliefs are science-oriented, and I am very skeptical, but now I have close friends who are esotericists, and I really enjoy passing time with them.

The book "The Courage To Be Disliked" by Ichiro Kishimi and Fumitake Koga. Help me a lot to understand myself and my insecurities.

Is it that you think you are smart, or smarter than the others? Is it about your deeper knowledge about a few specific subjects that interest you but not others?

I've been and am in this trap. I think I am not dim. I doubt it's genetic, because I have living relatives, so :) I am smart about USB-C accessories, nobody else cares. They are smart about living their lives to the fullest.

For me, I realized how insufferable my smart friends were, and I looked at people who I admired and whose company I enjoyed, and I realized humility was a key trait among the people I liked best. I’m still insufferable, though, but hopefully less than before!
