What everyone would LIKE to learn is the exact skill that’s going to be rare and in high demand the second right after you graduate. But usually what’s rare and in high demand is also new, and there are no qualified teachers for it. Anyone who knows how to do the hot new thing is making bank doing it just like all the college grads want to do. My advice is to get out of college and then spend the next four working years learning as much as you can. You’re not going to hit the jackpot as a recent grad. You’re maybe going to get in the door as a recent grad.
