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?

This week’s selected media, June 2025: Thomas Jefferson and The Choice

on June 15, 2025 in Tips

This week I finished: Thomas Jefferson: The Art of Power, by Jon Meacham: I’d been seeing lately how much the pattern today of repeats how Thomas Jefferson lived. Today, people recognize his flaws. We wish that on slavery he had acted differently. We wish he had, as a politician, acted more to end slavery. We wish he had freed his slaves. We recognize that his personal actions caused internal conflict[…] Keep reading →

My first Hillsdale College online certificate and why I took the course

on June 14, 2025 in Education, Freedom, Nonjudgment

I like American higher education. I don’t like how disconnected it has become to the day-to-day lives of most Americans. I don’t like how it has become overwhelmingly politically one-sided. I don’t like that that one-sidedness has led to professors moving from teaching students to learn to inculcating and indoctrinating them. I don’t like how expensive it has become. On the other hand, I consider the Trump administration’s attack on[…] Keep reading →

I wrote a poem: The Poem of the High-Fiber Diet (trigger warning: juvenile humor)

on June 13, 2025 in Addiction, Creativity, Humor, SIDCHAs

Am I going to get in trouble for a puerile post? Will it distract from my sustainability leadership focus? I hope not. I had a blast making the poem. Regular readers know my sidchas and standard operating procedures mean that I meditate as one of my first morning activities. Before meditating I go to the bathroom. Between my routine being so consistent and my diet containing so much fiber, I[…] Keep reading →

More on “How the liberation of living more sustainably feels”

on June 12, 2025 in Freedom, Models, Perception

I have to add to what I wrote last month on How the liberation of living more sustainably feels. In that post, I wrote I left out scope and scale I left out the scope and scale of the difference. Taking off wet socks feels liberating and surprisingly pleasant if you forgot they were on, but it’s still just physical sensations for your feet, a part of your body. Unlike[…] Keep reading →

Are there people who eat absolutely zero unpackaged food? I think so.

on June 11, 2025 in Doof, Nature

I was out in the park along the Hudson River picking juneberries. Not only was the food not packaged, I picked them myself. They’re incredibly delicious. The tree evolved to provide fruit to be eaten. I saw a lot of people picnicking on the grass, eating at the outdoor bar in the park, and eating while they walked. Every piece of food or beverage I saw them eating was bought[…] Keep reading →

822: Ryan Mandelbaum, part 1: Wildlife Is Everywhere, Including (especially) NYC (and where you live)

on June 10, 2025 in Podcast

This recording went far beyond my usual preference for recording with guests in person when I can. We met in Prospect Park on one of the peak birding days of the year. Tons of people were out with powerful binoculars and cameras. You’ll hear lots of birds chirping in th background and even people who knew Ryan coming up to talk to him. Nature is everywhere. We can enjoy it[…] Keep reading →

I increasingly feel like I’m in Monticello listening to Thomas Jefferson

on June 9, 2025 in Freedom, Leadership, Models

I feel increasingly like an abolitionist or anti-slavery politician around 1800 living in Monticello. Mainstream culture looks and sounds like Thomas Jefferson: He said some of the most important words in history on liberty and freedom. He knew how wrong slavery was. He knew owning people corrupted him. He knew he was violating his own values. Likewise, we all say we don’t want to drive a system that hurts and[…] Keep reading →

This week’s selected media, June 8, 2025: The Choice and The Wrestler

on June 8, 2025 in Tips

This week I finished: The Choice: Embrace the Possible, by Dr. Edith Eger: At one point listening to this book, I started feeling choked up. Tears started welling up in my eyes. I asked myself, “When has a book made me cry?” “Has a book ever led me to cry?” I continued to ask myself. As the book continued, I started full-on bawling at the experience of the author, how[…] Keep reading →

When they say “transition fuel,” they mean “more polluting and depleting,” not less pollution or depletion

on June 7, 2025 in Addiction, Nature, Podcast

If “transition” means we stop using the old fuel then there has never been an energy transition. You can hear more details when I post my next episode with Mark Mills, but it deserves more publicity. I recorded with him again after reading his recent piece We’ll Never Have an Energy Transition, in City Journal from the Manhattan Institute. I find his results compelling, as always. Every fuel we’ve ever[…] Keep reading →
