Quality is Subjective!
Who decides whether your post/design/caption/campaign is up to the mark or not?
Certainly, not the creator.
What is good for you, might not be for the one consuming it and vice versa.
At the same time, gone are the days when you could work on one creative only, try to make it perfect and pray that it works for the brand.
Now, there’s not one perfect thing anymore.
Quality is surely not dismissed here, however, the quantity is increased – so you can create more, in order to experiment more, in order to reach more people and cater to their individual interests.
