Anything worth doing is worth doing well.
The quote has good intentions, but it's flawed. Because if we wait for "well" or even "good enough," then most of the time we never end up doing it at all.
Instead of waiting for something to be perfect before sharing it, share it. Sure, people might talk about how much it sucked. But, at least they'd be talking about you. Instead of saying, "Who's that?"
Don't get me wrong. I'm not saying we should stop trying. I'm not saying we should be sloppy.
But launch before it's perfect. Some people will love it. Some people will hate it. Most people will ignore it.
But at least it will be interesting.
