Everyone knows that feeling left out feels awful, so it's important not to exclude others, Dr. Robin says. Is there someplace in your life right now where you can include someone who is feeling left out? Dr. Robin says we should all make an effort to include others.

Although we can't always include everyone, we can make a conscious effort to not leave people out on purpose. "I want you to decide that leaving people out unnecessarily is off-limits," Dr. Robin says. "Whatever you do, decide who it is you can reach out to today and keep them from feeling left out."
