O.K. lets keep it really simple.
One.
One,
then two.
Then it’s three.
Five syllables, Yah!
A Fibonacci poem for me!
To understand how to accomplish constrained writing like this, you need to understand the Fibonacci math sequence of starting with 0 and 1 and then adding the last two numbers together to add to infinity.
0+1=1
1+1=2
1+2=3
2+3=5
3+5=8
5+8=13
8+13=21
13+21=34
and so on and so forth…
This sequence is found often nature.
