My ecological footprint

on October 4, 2017 in Nature

Some environmental reading led me to a web page—The Global Footprint Network—that calculates your ecological footprint from your answers to questions about how you live your life. Go to the page and calculate yours if you want. I don’t know their assumptions or methods, so I can’t speak to its accuracy. With neither shame nor pride, I present my results: I seem to use less than many—little enough to leave[…] Keep reading →

Videos and a short history of my invention and Submedia, the company I co-founded in 1999

on October 3, 2017 in Entrepreneurship, Leadership, Stories

Ten or fifteen years ago most people knew me through Submedia, the company I co-founded to market I technology I conceived of in 1996. My invention The technology was a display we’d install on subway tunnel walls that looked to riders between stations like a movie screen outside the subway car windows. From a business perspective, we were a billboard company: we installed the displays at our cost, sold media[…] Keep reading →

Curating the daily newsletter

on October 2, 2017 in Blog

A slight policy change that I started recently: instead of posting every post daily, I’m going to curate somewhat and not send out for email every daily post. Some posts I write more for myself or I suspect won’t be as popular. This post, for example, I’m not going to send as a daily newsletter. It will still appear as a blurb in the weekly newsletter and on the blog.[…] Keep reading →

The Ethicist: Can I Spread the Word About an Unvaccinated Child?

on October 1, 2017 in Ethicist, Nonjudgment

Continuing my series of responses to the New York Times’, The Ethicist, here is my take on today’s post, “Can I Spread the Word About an Unvaccinated Child?” I’m pregnant with my first child, and concern for my unborn baby has prompted me to ask my friends if their children are vaccinated. One close friend, Y, has two young (vaccinated) children, and lives near another friend, X. Both Y and[…] Keep reading →

An ideal year’s outcome

on September 30, 2017 in Audio, Leadership, Models, Nature, Podcast

A recent workshop I attended had me write my dream of a “Year of Opportunity”—that is, what I’d like to make happen if I achieved everything I could. Normally we don’t share our greatest hopes and expectations since they enable others to judge us—for dreaming too much, for being unrealistic, for thinking too much of ourselves, for not achieving our dreams, and so on. So what? I’m going to share[…] Keep reading →

100,000 burpees

on September 29, 2017 in Fitness, Habits, SIDCHAs

I hit 100,000 burpees a couple weeks ago, on September 5th, if I remember right. Each ten thousand felt like a big milestone. Hitting six figures felt like it should be a biggest milestone yet. Instead I’m writing this minor post. It’s the biggest number with the most zeros, but the greater accomplishment is to see them like brushing my teeth—not that big a deal, just something I do. I[…] Keep reading →

How I feel after hard exercise versus watching TV

on September 28, 2017 in Fitness, Habits

Have you noticed the emotional difference between how you feel after exercising hard versus after watching TV? Comparing, say, rowing for 5,016 meters in 20 minutes, at over 900 calories per hour with watching TV or browsing the web for 20 minutes seems obvious but let’s compare anyway. Rowing, you want to stop soon after you started. It’s a relief to stop. TV, you can end up watching for hours.[…] Keep reading →
