Vibrations never lie. A person could be saying one thing and yet, thinking another. Get to the point where you pay closer attention to the vibrations you are receiving rather than the words you are hearing. Intuition is one of the most valuable mental tools you possess. Begin to consciously use it. Your rewards will be worth the effort.
You must strive to become much less susceptible to influences outside of yourself and much more inclined to trust the instincts and feelings that lie within you.
