True or false: College isn't for everyone?

I'm having financial aid troubles and I did my financial aid for last fall and spring. My classes hey dropping for nonpayment. I don't have the money to pay off for my classes and I don't wanna take a break from school because then it will take me longer to graduate. My friends said either get better grades or don't go to school and waste financial aids time because I'm wasting my time and financial aids time and there's jobs that don't require college. Just quite if I can't pass classes they told me. My friend said very brutally, "I don't wanna sound rude but do you really wanna be 30 and still in college? Why bother? Stop watsting financial aids time on degree you're not even going to get. You're not working hard enough and you're wasting your time." College has always been my dream but I guess my dream has to stop since I can't pass the tough classes. I tried so hard! I did but I end up failing. Should so quit college? Are my friends right? Or do a payment plan?
