It’s not about you. It’s about them!
Too many writers don’t get this.
The reader wants to know:
1. What’s in it for them?
2. That you understand where they are and what their problem is.
3. How you can help them overcome their problem.
4. Can you keep me entertained while doing the above.
So don’t fall into the trap of telling them all about you. They probably don’t care.
Don’t tell them all the wonderful things that you can do.
Instead take the time to first find out what they need, what problem they need solving.
Then find a way to write about that, showing you understand the problem.
Elaborate on the damage that problem causes.
Then show them your solution to their problem, making sure you paint the picture of how good it will feel once their problem has been resolved.
Oh yes, and don’t forget to keep them enetertained along the way. 🙂
