Field Notes

Weekly letters from a builder on the Osa Peninsula. Operator philosophy, the neuroscience of real change, and field intel from the rainforest. No hacks, no gurus.

One letter, most Sundays.

Written from the field — on building, on how people actually change, and on what one of the most biologically intense places on Earth teaches anyone willing to pay attention.

What you’ll get: one letter most Sundays. What you won’t get: 7-day transformations, morning routines, or a funnel dressed up as friendship. Unsubscribe anytime — no guilt trip.

Three lines of work

Operator Philosophy

What building companies in a place with no shortcuts teaches about pressure, decisions, and staying lucid.

02

The Science of Change

How nervous systems actually rewire — novelty, attention, consequence — used carefully, without overclaiming.

03

Osa Field Intel

What the rainforest teaches anyone willing to listen carefully.
