An investment...

A few weeks ago, I was told that I should consider taking time off from Grad school because of all the debt that I am accumulating while going to school. I was told that unless I am going to school to pursue a career in the medical field that putting myself in this debt is not worth it. I'll admit I am pretty deep in the hole but it's not like I am throwing my money away on things that I don't need, it's my education. I am putting my money into something that will help me have a better future. My best friend Darien once told me "If you ever need money, just ask, I don't consider it throwing money away I consider it a good investment. You're a good investment. Because I know you'll actually make something of yourself." Well I thought about this quite a bit recently, I've also thought about the crazy investments people make all the time and how they may lose all of their money but in the end they are still able to keep their heads above water. People invest their money in cars, homes, condos, and many, many credit cards,and are not only trying to pay them off, but they keep in the back of their mind that they will be paid off eventually. "It doesn't matter what you do the reality is everyone is always in debt, if it's not a home, it's a car, if it isn't a car, it's credit card debt, but an education is a debt worth having." Why shouldn't I invest my money into something that will help me to afford a home and a car in the future? Our American economy themselves are in billions of dollars in debt but instead of drowning and giving up our American economy is still fighting and trying. It hasn't given up, it's still surviving and so will I and every other undergrad and grad student out there putting themselves in the hole for something that will not only help but benefit them as well. I have decided to not giving up despite what a few people are telling me, I know what I am doing and it's possible that maybe in the end I will be in debt for the rest of my life, but as my mentor told me this week " So unless you become a doctor an education is not worth the money? That's bleak and pessimistic. Yes, it will be a burden, but a manageable one. Yes, it will take a long time to pay back, but it will be in small pieces, and that's what paying the bills is all about." I am not giving up and neither should anyone else...So here's my question to you...What are you investing in that people say you shouldn't be?
