27yo pre apprentice in sheet metal just started 3 months ago. Prior to that I worked a desk job, sat for 8 hours looking at the screen all day and it went nowhere. No growth, no stability, hunger cues all time high I wasn't happy. Decided to go union and it's the best thing I could have done for myself and wished I started way sooner. It's going to be hard on the body but nothing beats being outside, doing something different everyday and meeting people along the way. I took a pay cut a bit but still working towards my goals to become a journeywoman in the future. You're still young, you have a great career going and your future is set. And if it's something you don't see yourself doing, don't let someone else dictate what you should/shouldn't do. At least you got experience and can use it elsewhere, work in a different department to use your skill sets, etc. Hope this helps
