So you can go from this to this!

And the moment you think of "capacity", you can actually think of ways to climb up the ladder where you have more capacity in a day.

Then, another idea: total focus time is the wrong metric. What matters is capacity: how many usable blocks you actually get.

Here's an idea: model your day in terms of three numbers! a) how often you're interrupted, b) how long to recover, c) how much unbroken time your work needs. Simulate a few hundred days and you can see where things break. Sometimes with just one more interruption per hour.

Ever have one of those days where you're "working" for 8 hours but get absolutely nothing done?

Here's what that looks like vs. a day where things actually work out. Same 8 hours. I got curious enough to model why.

there’s nothing quite like opening the door to your hotel room for the first time is there. the gentle, calm euphoria of glimpsing this magical room you get to live in but don’t have to clean or maintain. the little thrill of seeing the bed you get to eat in without consequences

The Trump Administration Accidentally Texted Me Its War Plans U.S. national-security leaders included me in a group chat about upcoming military strikes in Yemen. I didn’t think it could be real. Then the bombs started falling.

In 25 years of covering national security, I’ve never seen a story like this: Senior Trump officials discussed planning for the U.S. attack on Yemen in a Signal group--and inadvertently added the editor-in-chief of The Atlantic. www.theatlantic.com/politics/arc...

A number of defectors from the Tesla brand said that a deal-breaker was when Mr. Musk extended his arm diagonally upward, palm facing down while speaking at an inauguration event for Mr. Trump, a gesture that resembled a salute used in Nazi Germany and fascist Italy.
