Whatever you are looking for outside yourself in another person or activity is also a part of you.
For example, if you’re looking for peace, there is a peaceful part of you. The problem is the part of you who’s looking for peace and the part who’s peaceful aren’t synced up – they have some disagreements that keep them from staying together. Work these out and you can have what you’re looking for. If you’re having trouble, just ask yourself “What is the peaceful (or any other) part of me doing right now?” and you’ll probably get a metaphoric image (in your imagination) showing you. Then try staging a conversation between the part of you who wants something and the part of you who IS that something. See what happens and try to work through it.
