Yesterday, early in the morning, my boss told me to take the day off.

My boss, of course, is me.

I decided I would do three things:

• Enjoy the wonderful weather.
• Get some exercise by taking a long walk.
• Figure out how to use the regional bus system to get to and from Denver (22 miles from my home).

Since I have a membership at the Denver Art Museum, I made that my destination. They have a fabulous exhibition of Rembrandt's prints right now. And although I'd been to it, I hadn't been able to see it all during my first visit.

​And so, using three different apps, I managed to get down to Union Station using public transportation. (Yes, I did get on the wrong bus initially, but it all worked out.) I took a nice long walk from the station to the museum. Ahhh—just what I wanted.

The museum has a studio where you can make your own prints right now—to complement the Rembrandt exhibit. Printmaking is something I've always wanted to explore, as I've found the whole process sort of mysterious and confusing. The previous time I'd been at the museum, I'd made this print using just a sheet of styrofoam and the tip of a pencil. (Hold your applause.)

Yesterday, when I returned to the museum, I ended up going straight back into the studio. Rembrandt can wait, I thought. I'm going to carve a linoleum print.

I was the first studio visitor of the day, and I got right to work. Again, I drew a simple bird surrounded by foliage. But unlike the styrofoam print, this time, I would need to carve out everything I did *not* want to make an imprint on the paper. And so began a remarkably tricky and time-consuming process of carving linoleum.

I don't think I raised my head once while I worked.

I heard mothers and small children and teenagers and senior citizens come in, make projects, and leave. I heard a tiny person demonstrate her fatigue with several tantrums. I heard a young girl talk about her tricky science project, involving planets and styrofoam spheres. I kept working.

Even though I overheard several warnings about the sharpness of the carving tools. I started to find them insufficiently sharp. Sometimes they seemed to be tearing the linoleum more than cutting it. But I persevered.

I heard people talk about getting lunch. I knew I should eat something. But I couldn't stop.

At long, long last, I felt like my carving was complete. I chose a paint color, applied it to my linoleum, and made a few prints. I hung one up to dry. I looked at the time—I'd been at it for FOUR HOURS.

It was the wonderful David Rakoff who taught me about this phenomenon of unbroken focus in a piece he did for This American Life called "Martha, My Dear." He introduced me to ​Mihaly Csikszentmihalyi and the concept of "flow." Flow is that sensation that's part absorption, part determination, and part hypnosis. It's when you're exactly where you want to be, doing precisely what you want to be doing. And happily, it's how I spent my day off.

This morning, I was given this dollar by a stranger. There were strings attached.

I was attending a "Caffeinated Mornings" event in Boulder. The featured speaker, Norm Shearer, posed a provocative challenge. He gave 30 audience members (including me) a crisp one-dollar bill each and asked that we do as much good with that dollar as we can—and then report back to him.

He's done this many times before, so he shared a few examples: A woman who bought a bag of clothespins, wrote complimentary and kind statements on them, and surreptitiously clipped them to people (on a backpack, say). A man who invested in a balsa wood airplane and took the time to play with a neighbor-kid who seemed to get left out of his large family's activities. A woman who lent order and courtesy to her apartment complex's chaotic dirt parking lot by spray-painting parking spots (which continued to be used after the paint wore away).

So, my ideas are percolating.

I'm reminded of my friend's cousin, who, finding himself completely broke in Paris, wrote out some recipes, used his last few francs to photocopy them, sold them on the street, and began his rise out of poverty.

I'm a writer, so I wonder if there are letters I could send. Or signs I could post. My daughter had a good idea—create and disperse a list of hotlines.

My daughter also thinks it's "cheating" if I ask for ideas here. I disagree. I say that when it's a good idea you're aiming for, the more minds, the merrier.

So: Any thoughts?

I had a dangerous mishap yesterday. And it never would have happened if I hadn't moved from Florida to Colorado.

Early in the morning, I began a drive to Denver from our home in Lafayette. It was cold outside, yes, but there was no snow. I noticed a bit of dirt on my windshield, so I gave it a squirt of windshield fluid and turned on the wipers.

Instantly, my entire windshield was covered with an opaque sheet of ice. Combined with the rising sun, I could see absolutely nothing. And the ice wasn't budging. It looked a little something like this:

With my wipers on high speed, I managed to make a little ice-aperture in front of the passenger seat. So I began to drive with my torso stretched to the right at a 45-degree angle. This went on for a few harrowing minutes until my full-blast defroster did its work.

Post-crisis assessment has established the culprit: windshield fluid purchased in Florida, which does not require antifreeze properties. I have now filled my reservoir with Colorado-appropriate fluid, and hopefully I won't have another blinding freezeout. Live (if you're lucky) and learn.
