This is the time to go to those places you've been dying to visit. Whether it's a road trip across America or a five month journey through Asia and South America, book your tickets and get traveling. Post-graduation travel is one of the best opportunities a young person has, as it falls right between studying and committing to a serious career.
Use your graduation cheer and re-invest it in your community, or a different community that needs it. There are a variety of volunteer programs that allow for commitments of varying lengths -- anywhere from a week to several months or more -- so you can find the perfect opportunity to fit in your time frame and your area of interest. Assisting in cleanup efforts in an area of recent devastation, teaching illiterate adults how to read, spending time at a food bank. The opportunities are literally endless. Visit Idealist.org or VolunteerAbroad.com to search for your perfect opportunity.
Use the resources at your school to find internship opportunities related to your field of study. A summer internship is a great way to boost your recent degree or diploma, and will help immensely when trying to land a steady job. Not only that, an internship is a fun way to explore potential careers, and will get your foot in the door early.
If working seems like the opposite of what you want to do once you've thrown your hat into the air on graduation day, then burn off some steam with a music festival tour. Once the summer months roll around, festivals pop up all over the U.S. Create a nice musical itinerary by following your favorite bands around the country, or following festivals and catching various independent concerts along the way. Festivals like The Warped Tour have dates and venues all over the country, while others, like Coachella, are a one-time event each year.
Some grads like to combine fun, work and cultural exploration, and you can do this by teaching English abroad. As a native English speaker with a four-year university degree, you'll be able to find a variety of opportunities to teach in almost any country in the world. Some require longer commitments, up to a year or more, but there are some programs that link you up with schools on a short-term basis. LanguageCorps offers the training required to become a teacher, and will help with placement abroad. Other companies, like Aclipse, will pair you with opportunities abroad without the upfront fee for training.
