Start with a Haiku then create 3 more Haikus using each line from the original.

When did I grow old?
In a moment? A year?
Transcendence is life.
When did I grow old?
Bright colors in crisp Autumn
Focus my reward.
In a moment? A year?
Wholeness created new value
A crescendo sweet.
Transcendence is life.
Seasons promote refinement.
Growth requires time.
