All Thoughts have consequences. The first place you feel the consequences of your thoughts is in the body. The only weakness you have is underestimating the power of your thoughts.
Science has proven our brain translates every thought we think into a chemical equivalent and then delivers those chemicals (for better or worse) to every major organ of our body by way of a messenger molecule. This explains why thoughts makes us feel the way they do. Not only does this explain why we feel the way we do but the this discovery means we have the power to heal ourselves of any disease and make any problem we have (including a lack of love or money) disappear from our life forever.
You don't get what you want out of life, you get what you THINK. Replace thoughts that make you feel weak with thoughts that make you feel strong and powerful and powerful and strong you will be come.
