thinking about a job in this industry

hey so for a while now i’ve been seeing more and more people getting into this type of job.. i was wondering if it’s really worth it.. im 17 turning 18 in a few months know but have been struggling to find work ever since i graduated when i was 16.. looking at people experiences it seems promising but how do i get my foot in the door and what entry level jobs are there and what do they entail?
