Mental Models & Self-Work

Frameworks that survive contact with reality. And the limits they don't advertise.

There's a version of "mental models" that's mostly LinkedIn theatre. Invoking second-order thinking the way other people invoke their CrossFit times. This shelf is the other version. The frameworks are real. The limits are stated. The application is to actual work and life, not to sounding smart in a meeting.

Some of the posts are about classic models like opportunity cost, sunk-cost reasoning, base rates, and second-order effects. Applied to freelance and solo-work decisions where they earn their rent. Some are about the smaller, quieter models that don't have viral names but that I keep going back to. Some are about self-work. Habits, attention, motivation. The honest reading there is that there's no clean framework. Just a few patterns that hold up if you respect them.

If a model in a post makes you nod and want to share it but doesn't change anything about your Tuesday, the post failed. The bar isn't insight. The bar is something you can use.
