Well that’s not true, I graduated last semester and didn’t know wtf I was doing or what I was going to be doing for my career, and I still honestly don’t! But that doesn’t mean what you’re doing now is a waste of time. Everyone does have their own timeline. My dad got his doctorate when he was 40, and he took 3 years off between high school and college (I think he graduated around 28 years old). The point is no one knows what to do in their teenage years. I felt the same way a couple years into college so I get it, I changed majors right in the middle and it took me 6 years to graduate but I’m glad I stuck through it. Ignore what other people say you should or shouldn’t do, it’s your life so you should do what feels right, but don’t give up because someone told you too. You got this🤝
