If you have never done any internet marketing before then its best to just pick literally anything, learn as much as u can about it, and try to make as much money as you - reasonably - can from it
Doing that, even if u picked a bad business that doesnt align with ur skills or interests very well, will still provide you with foundational insights on how online business works and what it entails.
Plus time is never rly wasted because many online skills are cross valued across different businesses. So if u fail at one, ur next new venture will go more smoothly usually. Remember also you can make money by doing almost anything if ur clever enough
Personally, i tried many things, picked one that seemed to align with my skills the best, focused on it, saw returns, then that stopped working, so im at a new point now, lol
