Instead of writing for a wide audience, write your book/blog for one specific person.Tim Ferris
The same thing needs to be implemented for business as well.
Build for that one person. Think about this person and how your product can make him/her tell “Woww”. How your product can help them, inspire them and make their lives easier.
When we find that one person who will love the product, we just have to find another 1000, 10K, 10M of a similar type.
