I agree. It seems that many people are worried about things being fair or working harder than someone else. If a person is late and missing out on something then it really only affects them and their plans. If you are in school "voluntarily" then getting the most out of the class for your benefit should be your focus. If we focus on unfair or injustice, it only affects us and our frame of mind. Stay positive, do you, and you will be better off because of it.
