Words fail, as they should...

So there is nothing to say

There is nothing to say

There is nothing

Is nothing

Nothing...

But gratitude

Now, if you take general "gimmick" of diminishing lines, you could insert all sorts of thoughts. An example:

Pain returns, as it must...

And to where can I turn for relief?

To where can I turn?

Where can I?

Where?

But to life

Shameless? No more so than second time somebody wrote a four-line verse. New words have created a new poem. In context of a longer poem, this copying of form in one verse might not even be noticed.

What is creativity if you don't create something? Use whatever tricks and techniques you need to start creating poetry.

3 - Read your manuscript backwards.

Backwards reading is antidote to "cerbrainiumitis" because a critical view of English language cannot be corrupted by flowing exposition you've massaged into sparkling prose. When you read your manuscript backwards, it's just a bunch of words, and those mistakes literally jump off page.

4 - Read your manuscript out loud.

When you're forced to say words your brain is forced to slow down and concentrate on material. Bonus - you may discover stumbling blocks like awkward sentence structures and choppy dialogue when hearing your book read aloud.

5 - Use right kind of publisher.

What do you do when that 5,000 print run costs $10,000 and features a grave error that cannot be dismissed? Your best recourse upon discovering an error is typically a sticker and a sense of humor. But a publisher that allows you to revise your book after publication (for a reasonable fee) means you're never stuck with your blunders.
