"This is the best I can do" vs. "It's not good enough."
Yes, it is another Seth Godin quote, there were a few in the draft backlog - deservedly so. Topic is failure to launch, innovate, improve and otherwise change.
For some it is due to a complacency - "if it ain't broke" type mentality. Change is hard and painful Launching is scary. So it is a lot better to stick to the course, keep churning out the widgets / 30 second spots / 300 word pieces. We lull ourselves into thinking that we have tried and discussed other ways, but this is the best for the time we are in in, the people we have, the customers we serve.
For others it is due to perfection - it could be a bit better, the design needs some work, we have to get another blurb, run another focus group, wait for a better window, avoid this week, don't compete with that event. When there is no deadline, it is all to easy to let it be dead on the line instead.
The way to improve, is to change. And to change we have to get feedback. And to get feedback? Launch. Get it out there. Call it a beta or a soft launch, but get it out the door.
one caveat; make sure you set aside time to listen, evaluate and then re-launch or re-boot.
