Hi,

Well different styles of writing requires different points to be mentioned. Motivation letter requires a set of different points to be discussed in the piece, similarly poetry also demands that and just like that any form of writeup has its own way of writing and systematic points to be discussed. But on a general note, any piece of writing should answer the following key questions. Again these are just subjective things, so it also differs from person to person.

1. What is the idea behind the piece?

2. What will the structure of the piece?

3. How to start and how to end?

4. What points to highlight?

5. Finally, how to mend it into a beautiful piece.

I hope this helps.

All the best.
