The business of academic writing.. basically everything he said in his speech (take the summary from the top comment)
When you’re expressing your emotions, don’t read every word you write in your head and think about how it would sound to the final reader… you will be filled with guilt and fear, trying to write a text that sounds cool/professional/smart/quirky/funny.
Pour out your heart/emotions in the form of text… just type away… type type type
And THEN format it to the final reader as a separate activity, later (?)
Running a business is a two part process.. like the diagram used by the Chicago university professor (develop it by adding more spectators).. do one then think about the other one later?
