Help for the future?

So I’ll be a Junior next year and I’ll be able to go to the tech center my junior n senior year (it’s across the street from my high school) but I’m interested in so much that they offer... what should i do?? I’m interested in software engineering, manufacturing, gynecology/obstetrics, maybe a nurse and basically architecture kind of I’m not very good at blueprints . I’m scared I’m going to waste my time in medical because I heard it’s not easy and very slim to get into it? Do y’all think I should just try one or like maybe talk to my counselors about it? Or if anyone is in these fields how your experience was please?

they offer

Automotive/ Aircraft / Cybersecurity

Pre-engineering/ welding/ hvac

Medical/ business/ cosmetology

Teaching/ construction/ plumbing

(Possibly more)
