Soldato
Take a hit and get trained up. Join a local collage and do an evening course and take holiday to do the courses during the day.
I was in a similar situation. I was a trainee carpenter when I was younger but dropped out of collage. Ive spent the last 15 years without a skill but worked my way up as far as I could go. My employee refused to pay me more money and said if I wanted more I'd have to leave. I felt used and abused but the big Corp who didn't care about me or my skills and drive to get to a decent salary and position.
I spent the last year's worth of holiday days working back on the tools with a carpenter who then asked me to go self employed and work with him as he has work coming out if his ears.
3 months later and I've never been happier. I have my own tools and van and I'm relearning a trade. I'm better off financially as well as in my home life. I'm also my own boss which feels great.
If you want it just do it mate, you can do anything if you try hard enough to get there. Im 37 and people told me it was too late to change my career path. Its never too late but every day you spend procrastinating is another day lost.
Good luck
Thanks for that Yep I really need to just pull my finger out and take the plunge as it's only going to get harder the longer I put it off.
