I graduated from college in 1972 and immediately started taking classes (in person back then, until late-90's) but in 2001 I decided to go for another degree. However, it was at the same school as I had been taking classes all those years and my GPA in that school was only a 1.64! I did not figure out how to enjoy school for myself until 1991 so the many courses I took in the 1980's were obviously not good grades (or completed), LOL.

While I agree that enjoying the course and wanting to take the class, being motivated was very important, by the time I graduated in 2007 I had a 3.26 GPA. If I had to do it all over again, the same way, I would.

Try the class and see if you can use it to generate interest and motivation? Doing "something" is the best motivator I know. Doing nothing and waiting does nothing and can trap one into waiting "forever"? You don't know if you will be more motivated next semester or not. But it is possible working as hard as you can on a course this semester will teach you more about yourself and where your motivation comes from and what you might like and how you do feel, etc. whether or not you get a "good" grade. Good grades can be gotten later, it's never too late to enjoy whatever you are doing. However, getting to where it's possible to create something to enjoy, it can get too late. I was 57 when I got my next degree and entered graduate school, already retired from work. I dropped out of graduate school partly because I would have gotten my degree when I was 60 and it was in a subject that did not make sense to me for that age, it wasn't like I would have practiced/gotten a job with that degree. I shifted interests and now I'm studying and working in a wholly different field but that experience was not a waste to me. Learning what you don't like or aren't good at can be just as important as learning what motivates you and usually is part of that learning. Thinking you are/are not motivated or might/might not do well, etc. is all in your head. You have to go there and give it a try to find out what is true, you can't just imagine it.
