Experiment with verb tenses in present and past.
Start in simple present, locating yourself in action.
If you need a start try: I hear drips from my house eaves. I walk to the corner.
Shift to simple past tense bringing the present moment into a relationship with a single past moment or an event ongoing until the present. Show emotions: fear, joy, anger.
Shift back to present tense.
Write about the verb shifts and what you gained from one or the other.
Did one tense attract more ideas?
How did one tense feel more appropriate for use?
Try the same sequence shifting from first person to third person. How does this expand your opportunities?
