Focusing on thoughts or images that make you feel good will enable you to be at a higher level energetically and, consequently, will draw to you a higher level of vibrational experience. In other words, positive thoughts will attract positive experiences. The reverse is also true. If you’ve fallen into the habit of negative obsessing and/or fear-based thinking, you need to know that you can shift to a healthier, happier mindset.
