It’s been at least ten years since I took a course of yours. The way you teach actually made sense and made things interesting. I took pride in doing well in your class, which was a feat at the time since I wasn’t taking school as serious as I should. Haha.

I finished my undergrad with a BS in Finance with an emphasis in Economics in 2016 and have been in the financial world the last ten years. It’s interesting and all but I continue to gravitate back toward economics, analytics, and statistics. As such, I found myself revisiting your site throughout the years to continue to learn. I’m now interested in obtaining my masters in applied economics.

That was really just a long winded way to thank you for teaching passionately and providing a space to continue to learn through the years.
