Growth Is a Search Problem

You start in fog, on a dark map, with an objective and no knowledge of which direction is uphill. The craft has always been a loop: hypothesize, move, observe, update. Hill climbing is one part of that loop. It can take you to a local peak, or up the wrong mountain if the proxy is wrong. One company optimized registered users. Another optimized people who actually came back.

AI changes the economics of the loop, not the geometry of the terrain. Agents can analyze, propose, ship, and interpret. You can now climb the wrong hill much faster. A rigid roadmap assumes the order of tests matches the size of the opportunities. Bandits waste less traffic on losers. A better strategy spends a small slice of budget mapping lever sensitivity first: poke the map, then climb where it makes a difference.

Before 0 to 1 Comes -1 to 0

Most founder folklore starts at launch. The harder stage is earlier: figuring out what is worth the next decade. In isolation it feels like a squiggle. Talent makes it worse, because every capability is one more path that must be ruled out.

The old advice was to raise and throw things at the wall. That is a weaker bet now. Software has already eaten the easy fruit. AI makes it cheaper to build and easier for thin traction to become a local maximum. A low-conviction fundraise can consume years.

Eighty Strategies that create Edge

Successful organisms, products, organizations, and networks overcome competitors by developing strengths along specific vectors. Often the advantage comes from an unusual combination of strategies rather than excellence on a single dimension.

This note catalogs roughly eighty such strategies, drawn from both biology and business, and grouped into categories: Accumulation, Price, Time, Uniqueness, Offense, Defense, Deception, Timing, Accreditation, Collaboration, Speed and scale, Ease, and Transformation.

Math Was Never the Wall

Most people leave school with a quiet wound from math. What they were given was calculation and procedure. What they were never given is the actual subject.

Real mathematics is the deepest tool humans have for seeing what is actually there. It is the language reality appears to be written in. Abstract marks keep predicting the physical world with absurd accuracy. Learn it and you are not studying a subject. You are reading the source code of how things behave.

Cognitive Debt in AI Coding

AI tools make it dangerously easy to fix bugs while skipping the learning.

The default loop is simple: paste a spec or error message โ†’ model returns a fix โ†’ symptom vanishes โ†’ ship. Over thousands of these interactions, the messy struggle that once built deep mental models quietly disappears.

The Salience Swap: Working When Your Mind Is Hijacked

Preoccupation is far more destructive to performance than distraction.

Distraction is external and removable. Preoccupation is internal. It occurs when an unresolved threat or uncertainty repeatedly hijacks your salience network, pulling your attention back every few seconds or minutes despite complete silence and no notifications.

Memory Is the Currency of Time

Time does not actually speed up but our remembered experience of it does. The difference lies between present time which always ticks at the same pace and remembered time which expands or contracts based on how many detailed memories we encode.

More memories make any period feel longer in retrospect. The brain however is wired for efficiency. It defaults to routines habits and familiar patterns to conserve energy. Once something becomes routine it requires minimal attention and creates almost no new episodic memories. This is why childhood feels vast with endless firsts while adult years can blur together.
