Form follows function.

Good design serves intent, not interface

A product exists to help someone do something. Every screen, interaction, and affordance should be evaluated against that single purpose and not against convention, trend, or what the technology happens to make possible. When the interface disappears and only the task remains, the design has succeeded.

Good design makes honesty structural

Trust is not built through polish. Trust is built through clarity. When a product is uncertain, it should say so. When it acts on the user's behalf, it should show its work. Surfaces that obscure how decisions are made, or that present guesses as facts, corrode the relationship between people and the products they rely on.

Good design is invisible to the user

Less, but better. Every element on a screen should earn its place. Complexity accumulates silently. A feature here, a state there, until the product collapses under its own weight. Simplicity is not a starting condition; it is something you fight to preserve at every stage of a product's life cycle.
