Buster is a mind-changer. Most of my life I considered tortoises to be plodding, simple-minded and uninteresting creatures. But then along comes this Russian tortoise into my life in October 2001 and she burned that opinion to the ground — and continues to do so.

Even though this clip ends in her failure to escape and me coming to her rescue, it’s a great reminder of how awesome she is and how incredible tortoises can be — how curious, how energetic, and how stubbornly unstoppable. Her ancestors don’t date back 200-million years because they just sat around the planet.

She looks at the almost two-foot-tall pile of river rocks I’ve arrayed on the left not as a way to be kept in, but as a way to get out. And though she suffers several setbacks in her escape quest, she ultimately gets thiiiiiiiiiis close to succeeding — all the more incredible when you consider how poorly equipped a tortoise is to such a rigorous endeavor.

Regardless of how inadequately outfitted Buster is to climb over a pile of rocks, “quit” is simply not in her vocabulary. Well… neither is “vocabulary,” but you know what I mean.

So on this Thanksgiving Day, I’m thankful for a lot of things and one of them is Buster’s indomitable spirit, which keeps inspiring me — especially so at this latter stage of my life when I’m attempting to scale my own disproportionate rockpile and achieve a place in a new career field.
