When people call your plan crazy, they’re often describing their own fear, not your odds.

When people call a plan crazy, they are usually describing how it would feel to them rather than estimating your odds. The reaction comes from imagining themselves in your position, with their tolerance and their circumstances, which tells you plenty about them. It is real information, just about a different subject.

Separate the feedback from the feeling by asking what specifically would fail and how. A real objection names a mechanism, and that one deserves your attention. Vague alarm can be received warmly and then set down.
