The majority of deadlines are not real and most people misrepresent the true meaning of them.
A deadline is the last possible moment a project can be completed. This instance in time can only be for a handful of reasons (at least in the world of video creation):
- The video is literally airing, being broadcasted, or being presented at an event
- There is a legal contractual obligation
That’s it. Two reasons. It’s being shown at an event or over the airwaves. Or you would be breaking a legal document. Any other justification is BS.
