Registering for classes

Why is it that I am always stressed planning my schedule for upcoming semesters instead of actually registering for the classes themselves? I am already stressed out about writing a 8-10 page paper along with taking two tests, so this registration problem just adds onto my stress level. For my potential major, most of my classes go from 6 pm until around 10 pm, and I will most likely be taking them in the fall. What's the point of these night classes? I'm a night person rather than a morning person, definitely, but I feel like I am going to hate taking night classes. I'll probably have to take classes during the afternoon as well, so it's like my entire day will be gone. I am also planning on taking summer classes to get a few credits out of the way and make sure I graduate on time, so I can't even look forward to no schoolwork until the second half of the summer. Hopefully, I will be able to get into all of my required classes when I register.
