Every short video should have a purpose.
That purpose does not need to be complicated. It could be to explain one idea, introduce one concept, or invite one next step.
Problems arise when a video tries to do too much. Teach, persuade, explain, and close all at once.
When a video has one job, it becomes easier to create and easier to understand.
The takeaway:
One clear purpose gives a video direction.
When you know what the video is meant to do, everything else simplifies.
