When you come across someone from a different background or culture today, start up a conversation. Even just a few minutes of small talk will help you get insight and new inspiration. You might want to try foreign travel, music, or even food. It's a good time for you to explore ideas and customs that are unfamiliar -- you might not like everything you learn about, but so what? At least you will have given your intellectual curiosity a good workout! To ensure your mind stays open, you have to stretch it.
