My presence is uplifting and joyful to others.

You don't get to experience your own presence, which makes this the hardest thing on any such list to verify. All the evidence is indirect.

Look for it in what happens near you rather than in how you feel. Do people tell you things? Does the conversation get less careful when you sit down? Somebody in every neighbourhood greets the supermarket security guard by name, and the guard's whole posture changes for it. Whatever you're doing that produces that in somebody, you almost certainly don't know you're doing it.
