As of the second quarter of 2021, Twitter had 206 million monetizable daily active users worldwide.
If someone has 1 million followers still 99.514% are out of his reach.
Still, he has an impact on a significant audience.
There are 7.9 billion people on the earth, a NY Times best-selling author sells his book to 2 Million people, which means 99.974% are not yet reached.
The author still has an impact.
Probably your prejudice that one who impacts all creates a profitable business is holding you back.
Key: Not everyone, but someone.
Target a tiny audience and you will have a scaling blog or website.
