This is not a revelation.
The funny thing is marketing is overlooked most of the times. Some say it is expensive, a cost center, a decoration to any business operations.
It can be if you will not create measurable results that show that it is a value for money.
Your product and service mean nothing if you do not know to who are you creating this for, or what problem are you solving by offering this product and service.
This is the first step in marketing. Understanding your consumers.
And by understanding your consumers, you offer a solution that solves their problem, that makes the world better.
Yes, by doing marketing you change the world.
I hope for the better.
And when you change the world for the better because your products and services work.
Your business will grow.
