Since it's Saturday, a day of errands. Put your small notebook in your pocket. As you go about your routine, look for images and write them down. Images are concrete. Everything we see, taste, touch, feel, smell (5senses). Use all of you senses today.
Look for images in action.
Take your list. Hopefully, you will have 8-10 (maybe more) and
create a poem.
Afterwards, distill your poem to a haiku. See what happens.
Hopefully you will have two terrific poems. You may distill to more than one haiku. It's up to you.
