Questions about a career to focus first

Hi everyone,

I need help on choosing which specialization to focus first? Full Stack or A.I.? I am more passionate on A.I side and I have interest on full stack too but base on my situation, I need to have a good income with a job that I can enjoy and passionate about.

I know all of them takes time to develop and gain mastery but which of them is more easier and has a higher chances of getting into an entry level job by building projects and networking without having a bachelor’s degree?
