  HAT Manifesto part 1 of 3, December 1, 2024, always some edits… Rubric Cube Veracity and/or Efficacy Summary 1- The world we see that seems so insane is the result of a belief system that is not working. To perceive the world differently, we must be willing to change our belief system, let the past slip away, expand our sense of now, and dissolve the fear in our minds. - William James 2- All experience has shown mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. - Thomas Jefferson 3- Wherever good fortune enters, envy lays siege and attacks it.

  From article What 10 Years of U.S. Meddling in Ukraine Have Wrought (Spoiler alert: Not democracy). Aaron Mate. April 30, 2024. Section 2.

  Weight at 163 pounds, got to 160 pounds five years ago and have recently been bouncing between 163 and 170. Common sense ways to lose and keep off weight are eat right and light and get lots of exercise. Main exercise is walking, do 1~2 miles most days. Over career worked as a salesman in the steelmaking, fasteners, and auto manufacturing industries, lots of travel in U.S., Canada, Mexico, and Japan. Have visited every U.S. city with a major league, MLB, NFL, NBA, NHL, sports team except Sacramento, have gotten as close as Travis Air Force Base. Often traveled on Sundays, much time on the road so could not eat right and get enough exercise so got heavy, up to 200 lbs. Was on commission and made enough to retire early, now eat right and light, get enough exercise, and now am spending most time reading and writing. Our Wick branch goes back to the brother of owner of the Wick House at Morristown National Historical Park in Morristown New Jersey and on back to Staines England. Have ...
