Okay, so in grade school, in high school and also in college, a long face from my parents would scare me, so it would in most part act as an extra motivator for me to get good grades. In grad school though, I always have the option of getting a job and fending for myself. If I want to learn something, I always have MOOCs covering me up. I can have the education without constantly thinking of being admitted to a good school or dealing with social pressure.
Now as I am into grad school, what specific points should I think of while studying? I really love studying, and enjoy the company of smart people; but sometimes I lose the extra impetus (which I used to get because of the fear of dealing with social embarrassment) in order to get good grades. Can someone just shed a different angle on the importance of getting good grades which does not include social stigma or the prospect of having a good job?
