There’s a rare breed of people in the world who are good, know they are good but aren’t overconfident. They have mastered their craft, know it, and are quietly confident.
Overconfidence or hubris is the road to folly, and the way is wide and welcoming. Humans flock to overconfident talkers because we conflate overconfidence with competence, and that’s when mistakes happen. Things aren’t checked, promises are made, people get sloppy, and disappointment follows.
Find and work with quietly confident people. Most times, you have to seek them out because they won’t find you.
