I am goin to start all over again if I didn't get my first choice? Or I should accpet second or third or so on choices as well? If I reject the other choices other than the first choice, can I afford to start all over again?

It's really really really good if I get my first choice for degree. But if, IF I doesn't, what should I do? Where should I go?

The choices towards my bright future is driving me crazy...
