Made Mistake? Move on

Yesterday I sent out an email with an embarrassing mistake: "know" without k in the topic line.
But what can I do? Once an email is sent, it is gone. Laugh, and move on, as a kind soul suggested.
Ok, onwards. Yesterday I did my first Youtube live! I drew mini-Storyboards for two coaches.
The first was Michala Storm who helps entrepreneurs gain clarity about their projects.
Second is Olympic gold medal winner and performance coach Joe Jacobi. It was so interesting to see the similarities and differences between both.
I might take the video down and split it in two because it is too long. You can watch it here for now. There is a lot of live wisdom being shared (and illustrated).
Should I start a Youtube channel for sketch-interviews?
