You don't actually have to be an expert in everything that interests you: For example, you can enjoy music without ever becoming an expert musician. Many people are fascinated by the images coming from the JWST without becoming PhD level astronomers.
If you think about it -- expertise isn't what makes a lifetime worth living. It's a sense that what you're doing has meaning: A meaningful life is what gives you that sense of "enough"-ness.
Meaning can unfold in different ways, but part of it is about being "in the moment" -- While you're learning music, you have to find meaning in that journey without wishing you were findign time for astronomy (or being frustrated that you're not actually Mozart).
I recommend the book "Why Smart People Hurt" which deals specifically with the challenges of smart people and finding meaning.
