No, it's the opposite. You seem to be falling into the money version of the "if I build it, they will come" fallacy. That's where I perceive the arrogance and a touch of "big fish in a small pond." To me, you haven't done anything overtly arrogant.

The fact given two people, most of the time they will not be a good match, often for mundane reasons, so you need to give people reasons to positively or negatively filter against you. Even weak filters like "I have experience in x or y domains and I like z domain, but I'm willing to talk to anyone" would improve your hit rates.

From the perspective of a founder (who's still pre-revenue, pre-funding), I spend a LOT of time filtering who to talk to just because I don't have the time to talk to _anyone_ who might be interested.
