What are you thinking at this moment? Have you ever wondered where your thoughts come from? Do your thoughts empower you or dis-empower you? How many of your thoughts are yours and how many are from someone else? These are some good questions and there are many more. Every thought you have has energy and every thought creates a chemical in your body that causes something to take place, joy, sadness, energized, open, closed, light, heavy. You are your beliefs and your beliefs come from thoughts, so back to the question are your thoughts/beliefs yours or were you given them, or were they installed by someone else? This is about quantum physics/mechanics and subliminal messaging (audible, verbal, visual, kinesthetic, etc.).
Are you thinking about how you can empower yourself or how you can be controlled by someone else or something else? You most likely aren't thinking about how you can be controlled and if you aren't but still find yourself in a non-empowered life at the mercy of just about everything, while looking outside yourself for assistance and change, you are out of control. Subliminal motivation can be a part of what is running/controlling your life.
Some things you can do: start to notice your thoughts and when a dis-empowering one comes up say something like cancel cancel (from Silva Mind Control, great stuff), Don't follow your thoughts around, let your thoughts just drift through, start to add empowering thoughts, intend to do something for yourself and others that will empower you and them (win, win), intend to do something and give that "good" intention more and more attention. And, Limit all commercial advertisements, avoid the negative, seek out empowering entertainment, listen to music that makes you feel good/relaxed. You will start to feel more positive.
