I want to get better at everything game development rated. Am I pushing myself too much? How do I prioritize?

I want to get better at my skills i have now. Art, ui/ux, music, programming, and game design. I practice these things, and I also went to college specifically for ui/ux and programming (stem related). But, i feel as though I could be better then what i am now. How would I prioritize myself better with me also working my part time job?
