I remember when that was a decent wage back in the late seventies... The four bucks an hour that is!!!
Shooot!!!!Thirteen buck an hour straight out of high school, and your boss will pay for the blue print class???
Man do you have it made!!! If you keep your nose clean, and keep up the good work, show that you're constantly improving, I bet he'll even pay for some welding classes in the not so distant future. ;) ;) ;) IMHO, stick with this job and transform yourself into a human sponge!!! Learn and absorb as much as you can because, all of the effort you put into it now will more than pay for itself in again - the not so distant future!!!
Instant gratification never lasts a lifetime ;) Ultimately the choice is yours, and I hope you make the right/correct one. :) :) :)
