You really can't spice up your own life without doing something drastic like traveling or seriously taking up a hobby.

Usually it happens as a result of meeting someone new and that they bring it into your life. Maybe hanging with a new gang or doing something that puts you in a different social circle and circumstance.

It sucks that you're about to complete your degree. Otherwise I would of said try joining a student club/societies or volunteering in college events. You meet heaps of new people this way and I think it's pretty exciting once you get significantly involved.
