When I first began writing publication was a measure of success, it still is to some degree. That external validation that you actually do write something that other people think readers might like to read.
Roy Marshall, a British Poet and someone with a few publications(collections as opposed to single poems) under his belt has just posted a piece called More thoughts on success.
He talks about external and internal success and the realities of being even a popular award winning poet.
There’s some choice advice there and I recommended it for Poets, indeed all writers.
Defining success for me at the moment is getting some long form poetry written. How about yourself?
