It really does take many negative thoughts and persistent negative thinking to bring something negative into your life. However, if you persist in thinking negative thoughts, over a period of time, they will appear in your life. If you worry about having negative thoughts, you will attract more worrying about your negative thoughts and multiply them at the same time. Decide right now that you are only going to think good thoughts. At the same time, proclaim to the Universe, that all your good thoughts are powerful, and that all your negative thoughts are weak. — Rhonda Byrne.
