Here's the first line
................................
it doesn't sound right
prosaic,  sterile, dry

I'll try again
*****
I quite like
shall start on second line

stuck for words
???????????????
I'll adjust the first line
OK, what follows seems fine

soliloquy 1
(  I have laid the foundation)

the pillars I have to *****
balance they must
and hold the main-frame
shouldn't be too low or high

(soliloquy 2: if I fail, the whole structure
would collapse)

I have no intention to rush
patience is what I require
from the workshop of my mind
and storeroom of my heart-   tools I must find

(on looking back-
that stage was my forging
heart, body, mind
the gruelling and testing)

(soliloquy 3)

now I re-examine
what's in my design
every word is like a *****
that must not misfit--to be fine

how I sweat and labour
into the project myself I surrender

the minutes tick, then the hour
the building is taking shape
behind schedule? Never mind!

at last, through the window
I look from the building done
how lush do the flowers blow
under a warm and smiling sun!
