Volunteer for work overseas and broaden your outlook
Of course you don't have to work abroad, there are volunteer opportunities everywhere.
You can make a difference and get a sense of achievement by helping out locally Check here.
Raise money for charity by being sponsored to have fun!
There are many organizations trying to raise money through sponsorships. You could be sponsored to do sky-diving, hang-gliding, abseiling, hiking up mount kilimanjaro etc. A great way to meet new friends and gain experience, not to mention raising money for a deserving charity! Check here.
You don't have to have a degree, there are many people who just need to be able to communicate in english and don't have a whole lot of money to spend on it.

Make a career out of arranging sponsorships.
Most charities are heavily dependant on fund-raising and sponsorship is a good way for companies to advertise. You can make a career out of marrying the two together Check here.
