i havent read the other replies, but do you really think 7,000 will last you for 3 years??
after all, you said you would be broke for the next 3 years, and you wont need money now since you have the 7Gs to buy whatever you want.
How old are you?
do you plan on providing for a family anytime soon?
How do you expect to PAY back the loan if you are "buying" whatever you want, with no income?
