Summarise Sunit's episode
Short answer
The obvious is invisible.
Long answer
Simplicity is not about stripping things down. It is about understanding what your user already expects, and then honoring that expectation. A door handle tells you to pull. A flat plate tells you to push. Good design whispers its instructions before you even think to ask.
There is a phrase that captures this beautifully: lunch and dinner. If a cafe serves meals but nobody knows it, an ugly sign fixes the symptom but not the disease. Design for clarity from the start, so you never need the patch.
The best designers have a low tolerance for things that do not work. Not just at their desks, but everywhere. In their kitchens, their drawers, their daily rituals. Discomfort is their compass.
