I had a stint one summer in my early twenties as an Executive Assistant to a CEO. Most of my role involved “managing” the CEO’s inbox. That meant printing out every email.
Twice a day we would have a meeting in his office. The CEO would read through the emails. He would dictate a reply while I scribbled it down in a notebook.
Later, I would go back to my desk and type out the email, pressing send on his behalf.
