It depends on your interest, and I say this because of my experiences.High paying skills simply means the ability you possess that employees provide you with increased compensation for. Base on my research, I am able to find some skills as one of the top high-Paying ones. Skills like; video production, Audio production, artificial intelligence, mobile application development, and product management. Which other skills you found worthy of being among the top high-Paying skills?
I personally can't go for anyone of those skills you mentioned, but I can see myself becoming a professional writer or copywriter.
