My Mission

My mission is to help change American (and global) culture on sustainability and stewardship from expecting deprivation, sacrifice, burden, and chore to expecting rewarding emotions and lifestyles, as I see happen with everyone I lead to act for their intrinsic motivations.

In my case the emotions have been joy, fun, freedom, connection, meaning, and purpose.



Systemic change begins with personal change.

Some of my values. What are yours?

Year 15, day 1 of my burpee sidcha

on December 22, 2025 in Fitness, Habits, SIDCHAs

I was 40 years old when I did my first burpee in 2011. Today I’m 54 and haven’t missed a day. Now I do more than burpees in what I call “my twice daily burpee-based calisthenics.” Daily burpees helped me develop the sidcha concept, which I consider one of the most important developments of my life. I’ve come to see sidchas as the most effective way to reach one’s potential.[…] Keep reading →

This week’s selected media, December 21, 2025: I Am Not Your Negro, Mulholland Drive, Wisdom Takes Work

on December 21, 2025 in Tips

This week I finished: I Am Not Your Negro: directed by Raoul Peck, based on James Baldwin’s manuscript Remember This House: You can probably tell that Baldwin’s views resonate with me. How he describes the perspective from the bottom of a dominance hierarchy. He attributes it to color, which I see as a proxy for access to a resource with no alternative, but the view is the same. Partly it[…] Keep reading →

Another winter solstice successfully handled. Tomorrow will have more sun.

on December 21, 2025 in HandsOnPracticalExperience, Nature

Today is the shortest day of the year, with the sun at its lowest angle at noon. Using only photovoltaic solar power, today I get the least potential for energy. It’s less cloudy than usual, so I’ll get some power, but a tall building a block south of mine blocks the sun for most of the morning. Actually, low buildings do too. Here’s a schematic illustration: Here’s a more detailed[…] Keep reading →

The second trashed Christmas Pagan Tree of the season, six days before Christmas

on December 20, 2025 in Habits, Nature

I can’t believe how little value people place on trees. Each year I ask myself if I want to bother taking all those pictures of trees people throw away. Am I going to change culture this way? I doubt it. Then again, I’m not hurting anyone and I’m going to post daily anyway. Then I see another Christmas Pagan tree being thrown out well before Christmas. This one appears denuded.[…] Keep reading →

Beethoven, Chopin, Mendelssohn, and my friend who met Albert Einstein in person

on December 19, 2025 in Art, Creativity

I wrote a few months ago about my physics professor who met Albert Einstein. He also plays piano, at least once even at Carnegie Hall, though a private event hosted by Steinway not for an audience. You might notice a resemblance to Einstein: He played at a private recital this week. I don’t attend enough in-person music performances, all the more for living in New York City. He played last[…] Keep reading →

The first trashed Christmas Pagan Tree of the season, a week before Christmas

on December 18, 2025 in Nature

Readers who have followed my blog over a year know that for the past few years I’ve taken pictures of the trees people throw out on the street. Since history shows that the tradition that Americans associate with Christmas came from paganism, and I’m concerned people who complain about “wars” on Christmas or Christians, I call them Christmas Pagan trees. That way if someone quotes me about how we can[…] Keep reading →

Dr. Larry Arnn on Churchill on technology and modern life

on December 17, 2025 in Freedom, Leadership

I recently finished Hillsdale College’s course on Churchill, hosted by the school’s president, Dr. Larry Arnn. If you don’t know, the school is as conservative as schools get. Arnn is also on the board of the Heritage Foundation, also as conservative as they come. Both institutions support policies and activities that pollute and deplete. To my mind, activities that pollute and deplete deprive people of life, liberty, and property without[…] Keep reading →

Turkish Get-Up Achievement and Freedom

on December 16, 2025 in Exercises, Fitness

Following up my posts Another 70-pound Turkish Get-Up, also more lifting personal bests and Two personal bests in a week: Freedom—and, speaking of health and fitness, New resting pulse: 38 bpm—I forgot to mention I finally achieved my third 70-pound Turkish Get-Up. For the meaning of the achievement, read the first link above. It’s funny that after at least a year of thinking about and planning it, the first one[…] Keep reading →

They chopped down the only two apple trees in a local park

on December 15, 2025 in Nature

The building with the clock tower in the picture below is my local public library. The iron fence behind the guy in the white hat encloses a park behind the library. It had two crab apple trees in it. As far as I could tell, nobody else knew it produced crab apples. The branches were higher than you could reach or even see the crab apples since they were the[…] Keep reading →
