I just don't care anymore. Any advice?
yannis: Being more than twice your age I can assure you of one thing. You will get these feelings in College, in your job and in your business. Even with your partner wife etc. You need to find a method that works for you to cope.During College I got terribly bored of lectures and was quite ahead of my class mates - and wouldn't be surprised some of the lecturers. I decided to infrequently attend lectures and studied for exams and assignments only. Piece of cake really to sail through. My social life improved by 1000%. I loved and love learning. I would go into the library and borrow all sort of interesting books from anthropology to physics (even dated one of the librarians). I was fortunate to study in London. Visited all the museums - the patent library (amazing). I worked part-time in a fish-and-chips shop (was a great experience to learn customer service). It was like physically surfing. I even took diving classes and went diving in a reservoir in Scotland. Really if you want not to be bored is easy. Refocus - you are there to earn a degree that is your target. Learning is a different and solo activity.It is much more difficult if you get these feelings in your work. Again you can channel energy into other activities, you can put research into areas of your job that others consider routine. Changing a job would merely put you into a similar spot once the novelty wears out. Divide your efforts into  - must do
  - this is my life things

The must do you do for survival and you handle them as best as you can. In the this is my life things you add the variety.
