Once, in a dry season, I wrote in large letters across two pages of a notebook that innocence ends when one is stripped of the delusion that one likes oneself. Although now, some years later, I marvel that a mind on the outs with itself should have nonetheless made painstaking record of its every tremor, I recall with embarrassing clarity the flavor of those particular ashes. It was a matter of misplaced self-respect.

If Earth were to shift to even longer days, we may need to incorporate a “negative leap second”—this would be unprecedented, and may break the internet.
~ Matt King and Christopher Watson from, The length of Earth’s days has been mysteriously increasing, and scientists don’t know why

The use of the phrase “may break the internet” made me smile. It’s not irony, and it’s serious. I do not want to think about what would happen if they inserted a negative leap second; The forward sort are bad enough, and don’t get me started on Daylight Savings Time. I digress.
This is a refreshingly clear, popular-science level article that covers the myriad reasons there is such variability in the exact amount of time it takes our magic marble to whirl precisely once around its axis. The very first thing most people never think of is how do we even precisely decide what “one rotation” is. (Hint: Astronomy.)

The essential power that confronting your mortality will give you—I call it the Sublime. Because it also opens up this idea of how amazing the world is that we live in, and how much we take for granted because we think that we’re going to live forever. It’s an incredibly important concept to me and it’s also very personal in the sense that I came this close to dying myself. I compare it to standing at the shore of some vast ocean. The fear of that dark ocean makes you turn away and retreat. I want you to get into your little boat and I want you to go into that ocean and explore it.

There’s an Etruscan word, saeculum, that describes the span of time lived by the oldest person present, sometimes calculated to be about a hundred years. In a looser sense, the word means the expanse of time during which something is in living memory. Every event has its saeculum, and then its sunset when the last person who fought in the Spanish Civil War or the last person who saw the last passenger pigeon is gone. To us, trees seemed to offer another kind of saeculum, a longer time scale and deeper continuity, giving shelter from our ephemerality the way that a tree might offer literal shelter under its boughs.

Trees are simply magical. Carl Sagan made a point in the original Cosmos series that everything uses the same basic machinery to read, and write using the same four “letters” of DNA. In a very real sense, trees are us with some different initial inputs. (Setting aside the more ephemeral, yet critical ways where we differ starkly from trees, like degree of consciousness, self-awareness, spirit, soul?) Stand next to an old enough tree and one is invariably transported to a higher level of thinking about being.

When—despite your best efforts—you feel like you’re losing at the game of life, remember: Even the best of the best sometimes feel this way. When I’m in the pit of despair, I recall what iconic writer Kurt Vonnegut said about his process: “When I write, I feel like an armless, legless man with a crayon in his mouth.” Don’t overestimate the world and underestimate yourself. You are better than you think. And you are not alone.

The popular history of spaced repetition is full of myths and falsehoods. This text is to tell you the true story. The problem with spaced repetition is that it became too popular for its own effective replication. Like a fast mutating virus it keeps jumping from application to application, and tells its own story while accumulating errors on the way.

If you’ve never heard of Super Memo, and you click over there, it’s likely to distract you for an hour. This article is both the origin story for Super Memo and for spaced repetition. I’ve read at least one other thing (I’ve not read this article in full, but I have read at least one other one), that is a comprehensive deep dive. Today, I’m sharing this in the hopes that you’ll glance over at it, skim around and realize that, since you will then be acquainted with Wozniak, I am not the most systems-crazy person you know of.

You know what the best thing about being an entrepreneur is? That you never have to experience self-doubt, the way people with normal day jobs do.
~ Hugh MacLeod
Ha. I was just kidding. Actually, as an entrepreneur, you have self-doubt coming out of your pores like cold sweat. And that’s on a good day.

Why is it so difficult to make choices that we know will be best for us in the long run?
~ Peter Attia from, Hyperbolic discounting: friend and foe of goal achievement – Peter Attia
slip:4upehy1.
Sorry for the titular word play. This should be read foremost to understand exponential versus hyperbolic decay, and then to understand how to get your future self to do what your current self wishes. Attia explains it in the context of imagining future rewards. It turns out that using one (to assess the value of future rewards) makes actual sense, and the other turns out to be how our brains work (because: survival drove evolution).
Snoring? No really, go read it. Because if you understand the two methods you can hack yourself by setting up your goals to play into your mind’s predilection to make the wrong value calculation. In effect, rather than set things up the way that makes sense which frequently leads to failure thanks to our brains, we set things up in a more complicated way to fake ourselves into getting where we want to go.
