Have you heard of the term “incubation”? When I looked it up online, the first example they gave was the incubation of eggs. It’s basically the time before they hatch. You can’t crack the eggs early. The chicken isn’t ready yet.
The thought here is that we should rush things that aren’t ready to be exposed. We all want to cross things off our list, and move onto the next project, but sometimes letting that idea simmer for a little longer can benefit the overall quality of the outcome.
