Will it sell?

I’m far too old to write a villanelle
A sonnet or a roundeau or  free verse
Besides I know my poetry won’t sell

I have my life  and living now to tell
But maybe you would like it better terse
I’m far too kind to write a villanelle

I  need another life time just to mull.
How I can avoid the writers’ curse?
I suspect  my  sonnets just won’t sell

Is the mind complete, might it be full?
I’d hate to have to write when in my hearse
I’m far too daft to write a villanelle

Get the knitting needles and some wool
I feel as if my brain is going to burst
Writing   sonnets  when they never sell

Yet writing of all options is least worst
Acting like a midwife or a nurse.
Am I too grey to write a villanelle?
Can I be sure my poetry will not sell?
