Literally what you focus your energy on in this world is what you attract. You know you are close to what you are wanting because you will feel it. It'll be a jittery, happy, energetic feeling.
Anything bad in this life happens also from your thoughts. A wave or frequency emits thinking about what you don't want in this life. A car crash, a demotion, a divorce, etc. All are a result of your thinking.
Here is an example of how you created a car crash with your thoughts. First, notifying your feelings during the crash can help you find why it happened. Most will find they have had negative thoughts during this instance. Now if they think back to the thoughts prior to this car crash , they will find they had thoughts that put them in the similar place they are in, being in the car crash.
Crazy right? I didn't know life work this way. We literally must watch our thoughts because they shape our realities!
Get rid of doubt and just know when you want something it'll come to you regardless if you can't map together how at the time.
