You are creating your life with your thoughts and your feelings. Whatever you think and feel creates everything that happens to you and everything you experience in your life. If you think and feel "I've got a difficult and stressful day today", then you will attract to you all the people, circumstances, and events that will make your day difficult and stressful.

If you think and feel "Life is really good to me," you will attract back to you all the people, circumstances and events that will make life really good for you.
