Here's a pretty dismal article about how much college is really worth:
Is a Bachelor's degree worth it?
College is expensive.
Consider working for a few years BEFORE you go, to help clarify WHY you want to go.
Don't go to find out what you want to do with your life.
Go when you have a clear idea of what college will get you, as in "I need to have a ___ degree in order to be a ___"
Don't go unless you have it paid for.
Don't pay for college with student loans.
