Vitrivius, in his ten books on architecture said that in architecture, there are two basic points: the thing being signified and that which gives it significance.
the first point relates to ideas, the second is about their context. It's the second that matters most.
When you have an idea, instead of rushing to the details and what makes it beautiful, the shortcut is to ignore the details at first, find what gives the idea significance, then go back to the details.
Premature detailing = detour.
Context = shortcut.
