I agree that focus is rare and critical, but I take issue with the closing paragraphs that suggest prioritizing focus over relationships.
What good is it to gain the whole world but have no one to enjoy it with? Of course this is simply another form of focus - choose which relationships to focus on. But putting intellectual pursuits above relationships is a lonely and foolish path, even if you achieve your dreams. If someone close to you suggests spending more time with them, you would be better served to listen to them than to cut them out of your life.
