If you haven't seen the video, Thomas is speaking to a young audience about the importance of personal freedom. He mentions the book The Motivation Manifesto (a book that I'm definitely going to read after I finish How to Win Friends and Influence People). In the book, there's a part that says:
Although I am grateful for where I am and I do enjoy my job and seeing young people grow and progress, I know I'm limited. I know that I don't belong. I know I don't fit. I've never fit in anywhere.
I have to make a life for me. I must go for my personal freedom. The countdown has started.
