What college classes should I apply for so I’m not shooting myself in the foot later

So I'm debating on going to college but I dont know what classes I should take and from what I've seen on this sub a lot of y'all have degrees that you cant use or employers just refuse to pay right for.Any tips on what I should do so I'm not wasting my money on something that is just a worthless piece of paper.Hope this allowed and thanks for any responses
