My annual letter comes out on January 25. I hope it spurs a conversation about the key issues affecting the poorest people in the world. So I’m inviting students from around the world to write your own annual letter and submit it. I’ll highlight the most innovative and inspiring letters on our website.

If there’s one message I try to get across everywhere I go, it’s this: Through innovation and generosity, the world has made amazing progress in improving the lives of its poorest people over the past 50 years. Now we face a choice. If we keep investing a relatively modest amount, we will extend this progress, feed a billion hungry people, and save millions of lives. If we don’t, we will tolerate a world in which one in seven people lives in desperate poverty.

In your letter, I’d like to read your thoughts. What do you think are the most urgent choices the world faces? I’m optimistic that if we can get a great dialogue going on this topic, world leaders are more likely to make smart choices in the future.
