I love most of what you wrote!
But I think (to use your example) being uncomfortable talking to people might be a sign of a deeper problem that has to be solved, not avoided. An introvert can cultivate extroversion and vice versa. It’s part of the growth mindset vs. fixed mindset. And it’s a lot more feasible and beneficial than trying to become 6'3 if you’re 5'10 as an adult. ;)
