It~s so hard waking up every day to just piles and piles of new grades and assignments every day. It teaches you that no matter whatever you do or how you view school, you will never actually be done or finished with your work. there will always be something new whether it's LLs, study guides, practice assignments, projects, or whatever. It feels like you are never smart enough, can~t do anything but fail the rest of your life and you just want to quit. But no, if you quit you won~t have a job or family or kids, and you~ll just be even more of a failure to your school and your family.
