Good news, though, is that this disjoint between your capability and your self-perception of your own potential and your dissatisfaction with the life that you are leading will eventually resolve itself somewhere in your mid-40s.

The next 20 years of your life after that have a very good opportunity to get substantially better.

If you are in your 30s and going through it right now, like myself, then just know there are brighter days like a decade away, stay the course and keep doing the work.
