Emotions can be dishonest. Don't trust them. They will whisper half truths. They're tempting, almost viable. But there is a subtle fault in their banters. If nothing else, be wary of them. A wise person will calm fluctuating emotions and wait until the morning, when all is new and clear and certain. Allow the voice of reason to be heard.
Yet, I give fair warning of reason as well. Often, he handicaps the greatest desires of one's heart. Perhaps together emotion and reason are at their best. Combined, they bring forth purposeful passion which changes lives.
