"As I begin to paint the scene, I drift into a right brain realm where I forget time and space and just sort of live inside this painting and the flow of color and brush strokes." – Artist Dimitra Milan
Single people want relationships, settled people wonder if they're missing out on something, traveling types miss stability, stable ones are restless, old friends want new friends, new friends miss old friends... The doubt is natural, and everyone you know -- yes, even that person -- carries it sometimes too. Allow yourself to be peaceful. Allow yourself satisfaction in what you have. If you really don't like it, allow yourself permission to make changes.
