I'm currently attending University, and it's going fine, but I honestly feel lost and confused alot of the time. I feel like I'm going through the motions but I don't really care about education. I'm fortunate enough that I'm relatively intelligent and can get away with doing the minimum and still get decent grades, but how long will I be able to keep it up before I actually need to put forth effort? I just don't feel very enthused about what I'm doing or plan on doing. I don't want to end up in a job I hate or not having a job at all after graduation. I just feel pretty uncertain about a whole lot of things. Is it normal? I'm 22 by the way.

Take a pen, a piece of paper and in 4 sentences write down where you see the 30 year old version of yourself. I did it and having to look at that piece of paper has helped keep my goals in sight and also give me hope.
"What if I have nothing to write?"
Then look inward and find what you're passionate about.
