Katie Kelly is still a university student, and she’s already traveled more than many people ever will. She has stories and photos to spare on her Tumblr, Travel Nerd. Volunteering has helped Kelly see much of the world – including nine weeks of solo travel through Africa and another volunteer stint in Mexico last year. You can view photos of her adventures at each stop, or read the emails she wrote along the way. Of if you just want to see cute dogs to cheer you up, she’s got that too.
