If you can afford to not immediately wageslave, try to specialize in something decent. If you can work hard, which is unlikely for this board, then STEM will generally guarantee a cushy future, maybe with the exception of basic bitch CS.
If you can't really work that hard, trades are still better than nothing. Sparky and HVAC aren't too bad.
If you can't even work hard enough to make it in trades, you better start on >>81679274's plan of eating dry cereal for ten years to save up money.
Also by "specialize", I mean actually git gud, not just get papers. Having papers is already not so bad, but being good at the shit you're doing is how you can make it even with a low-tier starting position. You can learn an enormous amount of shit from AI easily and for free, and AI is still very underutilized by normalfags, especially in low-IT-skill areas like tradies, so it's easy to get a competitive edge.
