College life

you learn how to be a "human"
most important thing you learned in your college life? probably the awareness of your real-self...you get to know who you are, you get to learn pre-real life outside your many years of school life, you realize that you no longer can depend on your teachers - in university, you have to seek detailed information yourself, as your lecturers will only give you the basic guidelines only...and hardship is very important in college life...
and then you realize you have to have enough friends because you never know when you need their helps in everything...

in short, you learn how to be a real human in this real world...

good luck in your college life !!

That lots of people are dumb. And how to read crticially. How to hold my liquor. How (and how not) to bust game on females.

I think that's all there is to know.

There are too many distractions. You need to focus on the important matters. There is a time for everything.
