One thing that Grant is known for always taking the initiative. One anecdote of his that I love is how that came to be. As a young officer in command he is was attacked and, surviving, he reflected on how terrifying that was. Instead of being afraid he just resolved to always take the initiative so that the other guy would be terrified instead.

I think Grant is among the most normal or relatable “great men.”

An absolute gem of a biography and, as you said, Grant was a fascinating human being.
