NEED ADVICE FOR TECH. JOBS

I am 24 yr old , prepared for defence exams, cleared written several times but couldn't get through in SSBs. I have done Bsc. Geology from DU. I am quite good in studies from starting, now I want to switch in corporate world in some upcoming field like AI, tech, softwares.... I am willing to do further studies in that field but due to lack of mentorship or someone known in such fields I don't know where to start from, what course to do, what to expect in future. I'm really confused what to do further with my life. My dream is to explore this planet as far as possible.

Tell me which fields are emerging and what course to do from where. All suggestions are welcome.
