What career advice would you give to young(ish) men. I'm about to turn 26 and am considering going back to university to get a technical skill after having dropped out first time around because I was doing a bullshit worthless degree. I've since been working in sales environments but do not want to be reliant on this for the rest of my life.

Ideally i'd like a technical skill that is automation proof, pays decently and means I could work from home partially in the future. I have an IQ of 116, if that helps. What are your thoughts on best path to go down/ feasibility of going back to uni and taking a pay cut etc?
