Short Story Compression

I want to write a short story ([WORD COUNT] words) about:
[YOUR CONCEPT]

Help me design it for maximum impact:
1. Single focused conflict (what is it?)
2. Entry point (where to begin for brevity)
3. Essential scenes only (list them)
4. What to imply rather than show
5. The ending moment (image/line to land on)
6. What makes this concept suited to short form
