Use your drive home from school or work or the store to catch up with a distant friend. Even if you only have three minutes. And if you don’t reach them, leave an encouraging voicemail. Add four or five friends to your phone’s speed dial list so that you can call them more easily more often. Think about someone to whom you often write messages, emails, or letters. Instead of writing, ask them to get together or, if they’re far away, call them.
