I think that the hardest lesson to internalize over here is, "every no gets you closer to a yes". Most hackers thrive on finding, solving problems and getting the solution just right. Intractable problems are apparent at the surface and they can get shrugged upon, at least for a while. The trouble wit people is that it isn't obvious when they are intractable, so there isn't a way to know if it's your failure, or if it's a fact about the client. Sometimes the person just doesn't want/need your goods, and no amount of persuasion will budge their mind, but it isn't possible for the seller to know that, so it's easy to chalk it up as a failure.

I think that if one doesn't recognize this subtlety, it's easy to fall spiral into negativity and lose hope. Since we're social animals, this comes across to the customer and it further reduces the chances of closing a deal, thus creating a vicious cycle that's difficult to recover from.

So, if you're a startup founder, do yourself a favor. Get some chart paper and magic markers, and paste a giant sign saying "Fail. Learn. Iterate."

(BTW, to be clear the learn doesn't imply that it's your fault, it simply means extracting lessons from the experience)
