How could I motivate myself to study philosophy without taking a class?

I find that I am much more motivated to study philosophy when I am taking a class for it and have a paper due or have to prepare for a debate. I will give a couple of examples.

When I was working on a final paper for my moral psychology class, I found that I learned a lot more than when I was merely reading the philosophers to understand them. I think the reason was that I had to respond to their arguments in detail given the tools I had at hand rather than just think about whether they were ultimately correct. The process was one of the most enjoyable parts of my college experience.

Again, when I was preparing for a debate over whether or not we have free will for another class, I found myself going into more depth in the arguments than I otherwise would. I worked out a systematic defense of free will drawing on a variety of authors, rather than simply contemplating whether or not the initial arguments were good in the abstract. Again, this was very enjoyable.

So, I'm wondering if there is some way to have these sorts of experiences without taking a philosophy class. I think the problem is that normally, when I study philosophy by myself, I get stuck on flaws that the initial arguments seem to have rather than simply taking the problems for granted and going into more detail on the arguments, because I'm trying to figure out what is ultimately true rather than simply make a plausible argument that I can defend against criticisms. If I had some kind of motivation that was external to the issue itself, like I had when there was a paper or a debate to prepare for, then I think I would learn a lot more philosophy.

Get a syllabus for a class and follow it. That way you can still get the material without the responsibility that a class will have. Write a couple papers over some of the material in the class, and ask one of the professors in the department if they would mind taking a look at it to see if you understood the material.
