In 2008 I volunteered with Volunteers Initiative Nepal , living in a Buddhist monastery in Kathmandu, Nepal and teaching English to the monks there. I wrote about it here, and I'm the President of the Board of a sister charity here in the states - so if you are interested in an experience like this, let me know!
In 2005 I fulfilled a lifelong dream of traveling to Egypt. I didn't write about it. But I experienced it fully.
