You are the creator of your own reality, and so you are not in jeopardy. You do not need to control the behaviour of others in order for you to thrive.
Your attention to things that you think they do that keeps you from your thriving is, in fact, what keeps you from thriving...
It is not what they do to you; it's what you do to you in fear of what you think that they will do to you.
Does this make sense? My take on what Abraham is saying is that too much time is spent worrying about other people - what they think, what they are doing, why they didn't do something you wished they had, why they said what they did etc.
You have no control over what anyone is doing, saying, or thinking.
The point is - it is none of your business what anyone else is doing, thinking or saying, even if it is about you.... it is their opinion, that's it, not truth. It is most definitely not your business what they think of you. Furthermore, worrying is wasted energy, and control is an illusion.
You worrying about their actions, whatever you think they may or may not do, is keeping you from moving forward. It doesn't matter what anyone else is doing, it is your journey and your vibration. You are in charge, you are the creator of your experience. You may think that whatever they are doing to you is slowing your progress, but YOU putting all your attention on what you think they do or being afraid of what they may do is what keeps you from moving forward.
You are creating stress in your life when you allow others to be the center of your attention. You need to concentrate on you, your life, what you are doing and leave the others to handle their own experience.
