As a man thinketh in his heart, so is he. Your thoughts are your doorkeeper that controls what goes in and what goes out of your heart, and your heart is like your inner home. If a prevalent emotion is negative, you can change your focus, thus changing the emotion. Emotions are based on where you’re putting your attention. You may hear inspirational information, that brings you positive emotions, but if you don’t actuate those emotions within 12-24 hours they start floating away. Establishing your doorkeeper is an intentional choice that you have.
