THE RETICULAR ACTIVATOR is a part of the brain the stays on alert. It's job is to make you notice some things and ignore other things (if you noticed everything, you'd be too distracted to function). When you buy a new VW, it seems like the whole world has bought VWs, because you notice them everywhere. That's the reticular activator at work.
Motivational speakers, business consultants, and authors of "success books" always stress the importance of having a clear goal. One of the reasons goals are so important is because they activate your reticular activator.
If you have the goal of writing and publishing a bestselling book, for example, you will start noticing things you've never noticed before. It seems the world is conspiring to help you out. You'll meet just the right people. You'll run into the perfect designer for your cover by an amazing coincidence. You'll happen to stumble across a magazine article that tells you about a software program that will really speed up your writing. And so on.
All these things are happening because your clear goal has set up the conditions for your reticular activator to work well. That's how it works. When you know exactly what you want, your reticular activator goes to work automatically to help you get it.
