While I’m in England, enjoy this post from 2020 (I have an even greater appreciation of Billie Eilish since this post was written):

About 7 years ago, I was at Zumba at the Wisconsin Athletic Club, and I was not feeling all that motivated. I had a move coming up, I was packing, and I was lonely, since both my dogs and my husband were out in Maryland.
I noticed a young woman in the row ahead of me who was really into it – her energy was on fire, her moves were smooth, and she seemed to be having a great time. Her t-shirt said, “Tosa East Senior Powder Puff Football 2007.” I did the math and realized that would make her 23. I decided that I was going to follow her and match my energy to hers. I joked later that she was my “unwitting personal trainer.”
Earlier this year, I started doing Zumba again at Brick Bodies and was really enjoying myself At the end of class, a woman (about my age) came up to me and said, “you’re really good! I was following you!” and I thought, “Oh my gosh, I’m someone’s unwitting personal trainer!” It felt good.
The reason I bring this up is that I follow a blog called Bulletproof Musician, written by a violinist and performance psychologist named Noa Kageyama. His most recent blog was on the topic of motivating yourself to practice by “copycatting a friend.”

Emulate, not imitate.
What does that mean?
According to Professor Paul Brians of Washington University, “emulate” is a more specialized term, meaning that you are striving to achieve something that someone else did (or surpass, as some definitions say). “Thus[,] if you try to climb the same mountain your big brother did, you’re emulating him; but if you copy his habit of sticking peas up his nose, you’re just imitating him.”
I emulated Miss Powder Puff Football 2007.
I imitate Julie Andrews.
Who is your “unwitting personal trainer?” Are you emulating them or imitating them? Do you know the difference?
(By the way, this song gave me a new appreciation for Billie Eilish.)
