Create a Haiku (traditional, senryu, or your own 5-7-5 or 17 syllable poem).
Then create something from what you have just created (especially if poetry is not your primary creative format).
If you are not a poet, find a haiku that speaks to you and create something from that.
Write a haiku/senryu about “the morning after”.
A haiku is a three line poem. The first line has 5 syllables, the second has 7 syllables, and the third line has 5 syllables.
Then write a longer piece interpreting the haiku/senryu in a totally different manner than you originally intended.
