The thought that everything we do must be enjoyable is the wrong attitude. I think that is the attitude that has gotten us in trouble. There are a lot of things in life that we have to do that we don't enjoy doing. Taking certain pre-requisite courses is an example. I didn't like organic chemistry, but I did like the idea of being a doctor some day, so I had to take Organic Chemistry.
The converse is also true, you can't have something just because you want it. Sometimes you have to work for things. You have to practice and try hard.
The simple fact of the matter is, if you don't have the will power to say, "I will do these hard things I don't like doing because I want these other things later in life." Then you are probably on the wrong course or simply not cut out for it.
We do have to make sacrifices and it sounds like that sacrifice for the OP is going to class, studying the material, and doing well -- even if he doesn't want to take that particular course.
I don't think that there's anything wrong with wanting to do only the things you enjoy. I would strongly disagree with the idea that doing so has gotten anyone in trouble.
Granted that sometimes the things you enjoy entail doing additional things that you may not enjoy so much, but if you really enjoy what you are doing then mostly you will be able to justify this as part of the big picture.
Personally I think that the idea that we all need to do things that make us money rather than the things we enjoy is what has made a lot of people over the years very unhappy.
Imagine working a job you hate for your entire life because you think, or have been told, that it's all you can do. We live in a society that allows us to surpass squandering our lives this way, we should endeavor to do so whenever we can.
