How many pieces of content do u publish a day?

I found this article that Gary Vee said you have to publish 100+ pieces of content a day. https://www.garyvaynerchuk.com/how-to-create-64-pieces-of-content-in-a-day/ Do you guy hit that number? If so, how do you do it? Is it hard to do it alone or as a small team? Do you have a team? What’s the hardest part to hit this number?

Thanks
