I was a working person who didn't know how to study data science as a non-major, so I only studied for certifications and was lost. I applied to graduate school but was rejected... I was worried that a career change was impossible and that I should give up when I came across this lecture. I feel reassured because I feel like I have a roadmap that I can believe in and follow. I'm going to the bookstore tomorrow and buy three books. I really hope that I can work hard to complete my skill set and get the job I want. Thank you for making such a great lecture. It's just the beginning, so let's do our best. Thank you again for the lecture.
