Too many cooks spoil the broth

Too many cooks spoil the broth or in modern times, shortened to too many cooks means that if too many people are involved in something, it actually hinders the process.
This proverb came from a story where soup was being cooked, and everyone in the house remembered separately that it needed to have salt added. Once every one of them had added some salt, the broth was too salty and was inedible.

Every time I try and do something on this project, someone else gives me a different answer and I can't get anything done. Too many cooks spoil the broth!
