  1. This one got me really confused. Because the number bottom right hand side of house looked like a 20 and then later he said it was a 26 and then even later he said 25. I threw my hands up in the air and gave up. but I got the gist of the lesson.  Or I think I did.

  2. Why? It should be one of the brightest days of your existence…for your illusions were swept away by your realization of the truth, and now your present is correctly aligned to proceed endlessly into the future. Everything started just a moment ago, and you're on top of the world…and you're wiser for the wear…who could ask for anything more from an endlessly improving self-image such as the one you're living now? "Not I" says the little stoner 🙂
