During personal quiet time, we develop self-respect as we get to know ourselves. The calm mind is a keener environment in which to do this and make smart decisions. Inner feelings are easier to understand and problems are more clearly analyzed when anxiety and agitation are absent. In silence, free of distractions, after your mind is tranquil, enjoy the calm or think about one important idea nothing negative. To solve problems, dump them into the silence.
Imagery works for some people.
Imagine walking through a gate into a peaceful garden. You see at the entrance a Grecian urn. Here you deposit all worries for the time being, as you stroll in and see a fountain tumbling into a pond with gold fish, surrounded by dozens of roses and all your favorite flowers. As peace settle over you, listen and wait. Answers may not come that instant.
