Do you have a Spiky Profile?
Some people run level. Roughly as capable at one thing as the next, strengths and weaknesses inside a narrow band. Their profile is close to a flat line. This isn’t for them.
This is for the other kind — the ones whose profile has a mountain range in it. Exceptional at the thing you’re exceptional at. Genuinely, conspicuously bad at things other people find trivial. You can hold an entire system in your head and lose the thread of a five-line email. You can read a technical spec in a weekend and not make a phone call you’ve been putting off for a month.
And then you get averaged. School averaged you first. Performance reviews average you now. Job descriptions are written for the flat profile and score you against all of it at once. The valley drags the peak down to a single number, and the number reads inconsistent.
For many of us the unevenness runs across time as well — three weeks of output, then two of nothing, judged on the pattern rather than the total. Peak and valley across your abilities. Spikes and troughs across your calendar. Both are in this book, and they don’t have the same fix.
Here’s the reframe: you’re not broken. Your system is misaligned. A car that pulls left doesn’t have a character flaw; it has a suspension problem. You’ve been trying to willpower your way out of what was always a mechanical failure.
The Spiky Profile is the operating manual for that brain. Underneath it sits one equation — Destiny = Direction × Engine — and the Four Forces that feed it: Probability, Time, Extrapolation, Consistency. This newsletter takes the machine apart one piece at a time: architecture vs. willpower, Position vs. Slope, the Valley of Invisibility, and the rest.
I’m Luis. Engineer by training. I spent years assuming the problem was me before I started treating it as a system to redesign. These articles are the manual I wish someone had handed me.
Start with the Field Guides
Two free workbooks, and the fastest way to find out whether any of this applies to you. The Architect’s Field Guide is for running your own system — nine modules, from the Probability Audit through the AI Protocol. The Manager’s Field Guide is for running a team that has someone like you on it: how to write a User Manual of Me, how to pair one person’s peak against another’s valley, how to plan when output isn’t a flat line.
Both are fillable. Type into them and save your answers, or print them and write by hand. Both are tagged to PDF/UA-1 and WCAG 2.2 Level AA and tested with a screen reader. A book about people the defaults weren’t built for shouldn’t ship documents that lock people out.
