Matt, I’m glad you are already finding this method helpful. Keep doing it! You can literally start to rewire who you are throughout the day, by simply using this one technique.
The technique is a variation of a method shared to me by one of my late teachers. The original method was developed/tested during a military intelligence project, run on 5 different US Air Force bases. Over 2,000 participants were in the original study. All the research behind it is what first got my attention. Then, after I started getting results, I was sold on it.
Keep it up and keep sharing, reach out for questions.
