What should I do for the next 2-4 years? [NJ resident, waiting for Rutgers FA, considering starting at community college, on NYU waitlist]

Don’t have this mindset. Believe that the best will happen.

I can’t emphasis this enough. Stressing really won’t help or do anything. You have been accepted and you should be happy about it. Even if you have to go to community college, which is not a problem at all.
