Intruders cause you to doubt what you can do and who you can be. An Intruder is anyone who says or does things that cause you to feel uneasy with yourself. You should not let these Intruders step into your space. All forms of doubt must be uprooted from your mind. Things you want to do are difficult or cannot be done when there is doubt. It is one of the greatest hurdles in our lives. The lack of confidence is the cause. Where there is doubt, the mind can never rest. Doubt is the root cause of unsuccessful people. It causes disordered thinking, which will not allow you to have a clear “unpolluted” thought to think. Therefore, it is on you to keep Intruders out of your life.
