I am looking for some advice.

Currently I am a teen and I want and I am getting into the programming world, and I have been kinda flip-flopping around from java Script to python to whatever. And I finally am starting to understand the point of each language and now I am a bit lost. I am interested in one day making my own startup as a programmer, and I find being a business owner to be very interesting, but I don't know where is the best area/niche to learn to give me the best skills that are in demand for me to able to have good chances in that market. I have done some research and people say that data science, ML, and AI are good skills to learn but I must admit I have zero interest in those. Anyone who understands what I am asking or themselves have been successful in making their own business please leave a comment. Thank you! :)
