“You are the attractor of your experience. As you look for positive aspects and make an effort to find good-feeling thoughts, you will hold yourself in a place of positive attraction and what you want will come faster.”
Esther and Jerry Hicks [The Teachings of Abraham™]
The Abraham material teaches a lot about emotions and the Law of Attraction. If you are feeling upset then you will attract more of that feeling even if you try to think a positive thought. It might be an easier path for you to think of something that causes you to feel good, happy, prosperous, abundant, free and then to bring into your consciousness what you desire so that you can link the feeling to the desire and thus create a more powerful magnet.
