We're about to launch an entirely new product to serve a market segment that is currently not served at all. Like any new product launch, the desire to "build until it's perfect" is a siren's call that has to be ignored for all the right reasons. Especially since, when building product, you know all the gaps, all the things you'd like to see, all the experiences you'd like a user to have.

This is probably the single biggest challenge I experience when making things: not the desire to get it right (since we'll do that in the long run, correctly), but the desire to be perfect out of the gate.

But we have to have the discipline to build, test, learn, and iterate.
