Check regularly on the negative suggestions that people make to you. You do not have to be influenced by destructive heterosuggestion. All of us have suffered from it in our childhood and in our teens. If you look back, you can easily recall how parents, friends, relatives, teachers, and associates contributed in a campaign of negative suggestions. Study the things said to you, and you will discover much of it was in the form of propaganda. The purpose of much of what was said was to control you or instill fear into you. This heterosuggestion process goes on in every home, office, factory, and club. You will find that many of these suggestions are for the purpose of making you think, feel, and act, as others want you to and in ways that are to their advantage.
