As owls and bats avoid the light,
Avoid the fault of being right,
Looking for the rest of the poem and author
It sounds a bit like ogden nash. No luck finding it though.
By the way, if you post something (like "still no luck?" for example) your old query goes back to the top. You have some more info here that might help.
"I am looking for the title and complete words to a poem I memorized 66 years ago.
As owls and bats avoid the light
Avoid the fault of being right
The blazing sun, undimmed, is shunned by everyone
While all approve a sky that shrouds
It's flawless blue with some faint clouds
The ending lines are:
Be sometimes wrong, Or under par
And being wrong, admit you are."
