"Want to see something neat?"
"Sure."
"Look! I edited this video! I added this, and this, and this. And, okay, you are probably rolling your eyes, 'Whatever, I did that twenty years ago.'"
"I'm not rolling my eyes. I'm excited for you."
When I was a college student, I had this retrospectively annoying attitude that, if someone already did it, I didn't want to learn about it, it had already been done. What I was doing at that time was being an asshole. I am not that person today.
Today, I am EXCITED when someone, anyone, kid or adult, shows me this new thing they learned how to do. I am bouncing with joy at their victories, even when that victory is very, very small. I am going to clap and cheer for that accomplishment, because it is new and you learned it, you did it.
