Inner voice is always right most of the time, because it knows us better than others and even ourselves. It's good to go by inner voice most of the time. Whenever you are trying to smoke, or whenever you are asked to choose one side in an argument, you are always worried about the result. During these times, your inner voice tells you what to do. If you don't follow your inner voice, you might be unhappy in the future. It's our own choice to either pay no attention to our inner voice or follow it and search for real happiness.
