Design Principles

• YAGNI: Don't build it until you need it.
• DRY: Extract patterns after second duplication, not before.
• Fail Fast: Explicit errors beat silent failures.
• Simple First: Write the obvious solution, optimize only if needed.
• Delete Aggressively: Less code = fewer bugs.
• Semantic Naming: Always name variables, parameters, and API endpoints with verbose, self-documenting names that optimize for comprehension by both humans and LLMs, not brevity (e.g., wait_until_object_is_saved = true vs wait = true).

Make sure homebrew is all up to date.

Make sure you have venv working, I think it just comes with python3.

Start a brand new RStudio project and open it in RStudio.

In the terminal:

python -m venv .venv

From "Jazz" by Toni Morrison

It's nice when grown people whisper to each other under the covers. Their 
ecstasy is more leaf-sigh than bray and the body is the vehicle, not the point. 
They reach, grown people, for something beyond, way beyond and way, way down 
underneath tissue. They are remembering while they whisper the carnival dolls 
they won and the Baltimore boats they never sailed on. The pears they let hang 
on the limb because if they plucked them, they would be gone from there and who 
else would see that ripeness if they took it away for themselves? How could 
anybody passing by see them and imagine for themselves what the flavor would
