I have been offerred a position in Georgia with the company i interned for-doing what i love getting paid squat.OR I can move to FLA-where my little sister is struggling with school, work and life in general. IN FLA I can help my sister get it together and get myself a job as a bartender, make mad $ and maybe eventually find a field biology job. WHat should i do? My friends and family are of no help "do what makes you happy" is not going to pay off my $60,000 in student loans.
