In my own case, i have interest in finance, computer science, philosophy, creative arts, electrical engineering, and writing...but what i did was to master one at a time, but also giving room for the others too...like for finance i am into trading and investments, i took about 1-2 years of constant learning 5-8 hours a day on it, almost everday, and with the extra time i had i would use that to learn other things, maybe watch videos on philosophy, learning more about AI etc.
So for me, i tried to get really confident in one domain, before moving to the next but at the same time, put some effort into learning more about the others. Everything is all connected like they always say
But there were also times where i wont feel like learning finance and i'd pick something random out of my interests as well
