Back in 2016, I wrote a post called "Manager vs. maker," where I cited an essay by Paul Graham that talks about these two modes of working. To quickly summarize, the manager's schedule is for bosses. It's a calendar broken down into units of an hour that gets filled with lots of calls and meetings. Things are said, and then the manager moves on to the next appointment.

Makers, on the other hand, can't operate in units of an hour. If you write, program, design buildings, create financial models, or do anything that requires uninterrupted focus, sporadic meetings are the most effective way to neutralize any sort of productivity. You need solid blocks of time. I was reminded of this post today because, as I said back in 2016, I like making things.

But it's even more than that. Deep work, reading, and strategic thought are, in my opinion, how you win. And to do these things you also need solid blocks of time. You need mental space. And the 12 minutes you have before your next call, isn't it. So I'm reviving my old post, and Graham's old essay from 2009, as a reminder to myself to be more ruthless about saying no and guarding my calendar.

Because:

Don’t your spirits rise at the thought of having an entire day free to work, with no appointments at all? Well, that means your spirits are correspondingly depressed when you don’t. And ambitious projects are by definition close to the limits of your capacity. A small decrease in morale is enough to kill them off.

Don't kill off ambitious projects. Block time for them.
