Fast feedback loops is the way

I've been thinking about the futsal effect - which is how Brazilian footballers developed superior skills through a constrained small-sided game with 5 on each side, then moving onto a full football game with 11 on each side. My understanding is the constraints are designed such that the most important and difficult skills are trained in a fast, immediate feedback loop.

When I apply it to building stuff I've realised a lot of the time there's a tendency to put too much weight on things like performance and aesthetics. Most people don't reach the point of needing to worry about those things. They're not the bottleneck. You can just use bootstrap for aesthetics and worry about being original later. I could be stupid but Python + Quart + Sqlite(with aiosqlite) + HTML/CSS/HTMX/ and whatever necessary javascript you need seems enough (at least for SaaS).
