I would travel back to 1985 and tell my younger self to knuckle-down, because college is much tougher than high school; put the lifeguard salary in savings and spend the drugstore salary; move out on your own for a bit and lean how to be responsible for yourself; and the hot guy leaned up against your car is NOT all he appears to be, that will be 7 years of hell you will never get back...go back to your first love, because he loved you the most.
