What this means is that the people around you, constantly under the pull of their emotions, change their ideas by the day or by the hour, depending on their mood. You must never assume that what people say or do in a particular moment is a statement of their permanent desires. Yesterday they were in love with your idea; today they seem lukewarm. This will confuse you and if you are not careful, you will waste valuable mental space trying to figure out their real feelings, their mood of the moment, their fleeting motivations.
It is best to cultivate both distance and a degree of detachment from other people’s shifting emotions so that you are not caught up in the process. Focus on their actions, which are generally more consistent, and not on their words. Do not take so seriously people’s promises or their ardor in wanting to help you. If they come through, so much the better, but be prepared for the more frequent change of heart. Rely upon yourself to get things done and you will not be disappointed.
