34. Learning Economics. Reading Principles of Economics by N. Gregory Mankiw . I didn't take a course in Economics while in college and am trying to make up for it and build a better understanding of how the world operates.
I finished the Machine Learning specialization offered by UWash on Coursera a few months back, but I am not happy with my grasp on the subject and plan to dive deeper with a project and few books in next few months.
