Project 1:
My oldest son is doing advanced mathematics and, boy, I don’t remember studying this at all! Spent time looking through the instructions, looking through YouTube, etc, to find out the formula and function. This probably took up most of the day!
Project 2:
Practiced piano for 20 minutes or so from the free content in Piano in 21 Days.
Project 3:
Played a few songs on the guitar (the ones with simple chords and not so many of them… 😉 )
