People don't understand that you can solve a lot of problems in life by doing nothing at all. The reason we find ourselves with the same problems over and over is that we're constantly stuck in a loop of doing the same thing, again and again. We're simply so programmed and conditioned that most people aren't even aware of it or thinking about it. They really don't notice that they're repeating themselves, the same actions, the same problems, and round it goes again. It can be in a relationship, at work, health problems or any other problem in life, and it's because we keep doing the same things and then get the same results. The best thing to do is to stop and do nothing.
Why do we do what we do? Because we believe it's the thing we're supposed to do. In other words, our belief system decides our actions. Put simply: every action you take comes out of your limiting belief system! So if you want to shut down a limiting belief, all you have to do is nothing! If only because doing nothing is already doing something different.
All of our lives are algorithms. If you react emotionally to the things you don't like or don't want in your life, you've just invited the universe to keep supplying you with more of those things. And the other way around: if you react only to the things you do love and do want in your life, that's an invitation to the universe to keep supplying you with more of them.
Sometimes the most powerful action is to do nothing. An active choice not to react can be stronger than any action. In our reality, the passive thing is actually the active one. Stop reacting to everything.
