A fellow parent and I are working on putting together a Python class for our middle school children. In the first lesson, planning to cover:

One of my interests lately has been dance. I recently joined the YMCA and have really enjoyed the Zumba and BodyJam classes. Simultaneously, I came across a Danish singer by the name of MØ and her song “Lean On”. In checking out the song I ran across the music video, which was filmed in India. Needless to say, with my site ISpeakHindi.com I found that to be interesting.

Here is another instructional video that walks through the dance in a lot more steps and more complete.

Two sales men go to Africa in the late 1800s to see if there is an potential to sell shoes. One of them telegraphs back (telegraph here does not refer to an iPhone app, but rather a mode of communication the predates the internet, which didn’t always exist), “There is no potential here, no one wears shoes.”
The other salesman telegraphs back, “- …. . .-. . / .. … / .- / …. ..- –. . / — .–. .–. — .-. – ..- -. .. – -.– / …. . .-. . .-.-.-” (morsecode.scphillips.com/translator.html)
Likewise, there are only about 3% of the population that listens to Classical Music. Some in the industry say if they could just get it up to 4% then the industry would be saved and that there would not be an further orchestra closings. But Benjamin Zander proposes that maybe many more people (most people) would like classical music, but they just do not know it yet.
Take a look at his TED talk and let me know what you think.
I just read a great article on TheNextWeb: thenextweb.com/entrepreneur/2015/05/30/too-busy-two-little-words-one-big-lie/
Starts with:
I’ve never heard of a highly creative or successful person being too busy. Let me rephrase that: I’ve never heard of a highly creative or successful person that I respect being too busy.
Ends with:
I’m an entrepreneur who isn’t willing to live someone else’s life. I measure my success by the things that make me happy, not by things that are glorified by our society.
Stop being busy. Start being honest with yourself. Make changes in your life. It will be scary, but it will be worth it.
With a lot of good advice and observations in between… definitely worth reading.
