After graduating school

I will graduate on June.This let me think a words that a teacher said.

Hs said "You will forget eighty percent what you learned in school after
graduate school. The twenty percent is a ethos how to slove problem."
The words let me think a lot. I think he is right.
Because we maybe not do what in the future about our profession in school.
But in the four years, we have be practicing how to slove problems.
And how to use tools we need and how to cooperate with other people.
The important is what attitude should we have.

Anyway,no matter what you learned,the important is how many learning
ability you have.
