I'd suggest putting yourself in a different context for a while. Go live a foreign country for a year. Get a summer job on a construction site. Do a bike tour across a continent. Spend a winter as a ski-bum. Spend a summer fighting forest fires or planting trees. Join a soccer team. Take up skydiving. Dive deep into the local club scene. The idea is to put yourself in an unfamiliar and preferably uncomfortable situation for long enough that you learn to deal with them. In the process you'll learn a lot about yourself.
