What you wished you learned in school?

For those of you who went on from undergrad to graduate school. I am about to complete my MBA in December and there are several things that I felt my school left out of the program that I thought should have been included. In my opinion graduate school is not designed to prove that you can learn things from text books, but rather to prove that you can think critically and not simply spout things off that you memorized (like in undergrad). I feel like the school I attended fell short of class participation and class discussion, more real life career experiences, legitimate real world situational analysis, the ability for my professors to tie some of the classes together, and some overall general knowledge. Does anybody else have issues with what they learned in school and wished they had learned things in school they eventually learned the hard way?
