Life becomes pointless when you don't have any goals.
It becomes really twisted the moment you graduate because you need to form your own goal. You do not have a time limit or number of years to achieve a certain goal you want to attain in life. It's like you form goals for yourself. You also give rewards to yourself. It's not like there is an achievement unlocked anymore. It's like you are now entering the survival mode.
Life's really beyond a 4 years course.
If you're not mentally prepared when you chose your course, if it was because of the so-called norm, or what people used to do and you think you have to do it because they are doing it... it's 50/50. And it sucks when you fall on the lower half.
But then again. What would you do?
