Spiritual beliefs are best spoken with actions, not words.
If you see someone who needs cheering up, rather than ask them to smile, give them a reason.
Smile at them, give a compliment, help them with a difficult task. If you see someone struggling, don’t ask them what’s wrong, ask what you can do to help.
Wait until they ask you why you are so happy all the time, then you can tell them about the Angels on your shoulders.
