Humbling epiphany...
You can't do everything!
So, focus on your roots and what you're intrinsically inclined to do.
Whether it's music, biology, tech, sports, etc.
Find that "thing" or few "things" that define your existence or purpose, and let it be your North Star.
You can always change, but as long as you're inclined and willing to adjust, there will be no issue.
Incorporating or mixing facets of your purpose into your work or life makes everything feel fulfilling, but do not aim to achieve everything on this Earth.
Be a generalized specialist; have three broad, overarching umbrellas of your natural inclinations and go in-depth within each of them to achieve satisfaction.
You can't spend every day doing "everything"; keep it focused.
Focus = Happiness
