Exactly, and unfortunately most of us don't gain perspective until we are bitten. Loans and parents paid my way through undergrad and I skipped a few classes here and there, I won't deny it. I was one of the luckier ones to get a good job post graduation
Then I started grad school about a year ago paying my own rent, bills, books, tuition, etc. and I'll cut a toe off before I skip these classes and don't participate. School's expensive, yo.
Shitty jobs are a different thing when you are living rent free on someone else's dime.
This the main take away I get from the posters lament. He doesn't understand the value of money yet and I'm guessing, like quite a number of college students, parents are still footing the bill for the vast majority of his expenses.
In the end of the day motivation won't come from an internet forum, the poster won't fully understand the value of what he's skipping until he deals with the real difficult challenges of life.
