Life is a huge university. And not everyone go to it is a student. If you find yourself in it , first you must know why you are there. You can be a professor, a chief, a chef, a cleaning personal, mail man …etc.
The main purpose of the university is teaching students. The vast majority are students. Students are on different levels, majors, time spans …. Some quit early, some graduate fast, some takes their time, some switch majors, some repeat and repeat, some can’t wait to finish, some wish they never got there and some wish to go back again.
