Yes Hal, later study is always an option. My own not so young young lad is a chippie by trade, but managed to get a masters in applied pyschology, when construction took a belt in the last recession, and is now studying for a degree in data analysis. He went back on his tools when marriage was on the horizon a few years back, and now is off them again, as he got a good job as a finishing foreman with one of the big outfits, and has had other good offers to move again. There is no doubt that the application to study etc, was of use during interviews.
