The solution?
Remember this simple sentence:
Pointed is better than broad.
Is called:
A narrow and specific audience is much better than a broad audience if you want to write a book.
Why?
If you write a book for the masses, you have to follow the masses.
There is a law:
Customers are chasing after the specialist.
With a precise israel telegram screening target group, you can address your readers much more specifically.
And do you know what happens then?
They also feel addressed.
And buy the book.
It becomes even clearer when you apply it to doctors:
If you need heart surgery, you find a specialist and practically beg him to treat you.
So you have to narrow down your audience: It has to be so specific that you are practically one of the few who can help them and they practically beg you to let them buy your book.
