Bad Idea? Y/N?

Is it crazy for me to take three 400-level English literature courses next quarter?

I don't have to take them, but two of them I definitely want to experience (Tung! Again!) and the third just sounds interesting. Seriously, is it crazy to do this to myself when I technically don't have to? Should I back away from the heavy reading material before it's too late?

Guess I'll wait and see what my adviser has to say to me.
