I can't help but agree with the statement that "If only someone had told me by poking me in the side..." I spent a lot of time studying on my own, and I want to use the time I spent to poking someone in the side. I want to give them confidence. I wanted to know why this was important while studying on my own. I was touched by the Intro in the appendix. There was a time when I studied on my own, but I gave up. Since you've been poking me in the side since the Flow lecture, I don't think I'll give up this time. Thank you.
