As much as I love watching theprimeagen during leisure time, personally I think he loses control out of sheer enthusiasm and instead of teaching you, which is his original intention, he just shows off with fast typing, shouting like a goofball, and bounces up and down like hyper-caffeinated person which distracts me, let alone to take him seriously.
Just watch this video https://www.youtube.com/watch?v=FknTw9bJsXM which is such an important topic, yet I have very hard time following...I prefer the format of pluralsight and the old lynda.com style of teaching.
