Why do complex, large-scale designs still stump me?

You can design most landscapes now. Say that plainly, without false modesty. The ones that still beat you are the large, complicated ones — too many pieces, too many people, too much to hold in one head at one time. Here is the honest reframe: this is not a bigger version of the skill you already have. Designing one clear space is a private act. Designing a large, complex one is a shared act. It asks for coordination, not just vision. You are still judging yourself by the wrong standard — as if a better designer would simply see it all at once. No one does. Not at this scale. What is in your power is not genius. It is structure. You can choose how the work gets broken into pieces, who owns each piece, and how those pieces get checked against each other before they're built. That is a team's work, not a solitary one. Stop searching for the insight that will let you do it alone.
