Want a very enjoyable productivity hack? I grew up loving music. In 7th grade, I got kicked out of choir class for smoking in the boys' room!  I have been singing since I was a kid and picked up the guitar in my thirties.  There's not too much music I don't enjoy. However, I sure do wish I would have discovered Mozart years ago.  Next time you're working or driving, turn on Mozart. You won't regret it! There's something magical about a symphony played in a major key.
