I don't think that many people stop to think about how powerful a single thought can be. A single thought can manifest itself into hypotheses and theories, or even physical objects. What I mean by physical objects is that, every invention started with a thought. How you think translates into what you say, and how you act. This is why I always say, "Watch your thoughts". Your thoughts, whether positive or negative cam also have an effect on your emotional health. Please watch this sermon that Bishop T.D. Jakes did on the power of your thoughts.
Make it a point to watch your thoughts this year, and don't let anyone influence the way you think. Have a good new year.
