I maintained links with my students and others in the country, and with my fellow Peace Corps teachers. Every summer we spend five days together: They are the best friends I have. I know many former volunteers who stay in touch with their village, or with friends, over many decades. The Malawi Children's Village, an orphanage, was started by former volunteers and has grown into a substantial project.

Like many people who have been affected by such an experience in a distant land, I did not come all the way home; nor did I leave that experience behind. It stayed in my mind, it informed my decisions, it made me strong. To all of this, there are people who will say, "What's the point?" But those are the same people who'll say what's the point of writing a poem, or learning a language, or going for a hike, or lingering on a wooded path to watch a bird flash onto a branch.

Whenever someone asks me what I think he should do with his life, I always say, First, leave home. Get out there, where if you care to listen, you will find many other people dreaming of making connections and changing the world, just like you. The only mistake is in thinking that you will make an important difference in the lives of the people you're among. The profound difference will be in you.
