She talked to herself all of the time because she loved her own sense of humor. – Queenisms™
We crack ourselves up all the time and frankly we suspect you do too. Having a good chat with yourself on a regular basis, and allowing that sense of humor to uplift you, is a very good thing. Look for the humor in situations that are causing you distress. Notice those things you cannot control (most things) and find the silliness in them. Listen for things in every conversation that tickle you. Amplify that. You’ll be glad you did.
