Now that Fall is creeping up on us, this got me thinking of all the students getting ready to pack up and start their new school year. I remember learning a lot at school, but to me, the bulk of the important lessons came post graduation. That's because I'm finally getting a taste of what "real life" is like, and am dealing with issues that can affect my finances instead of just my GPA. There's definitely more on the line when you're done with school.
I'm asking, what's the biggest lesson you've learned from working?
