Here is an unfenced existance
Any memory for the most part depending on chance.
Many modern novels have a beginning, a muddle and an end.
I think a young poet, or an old poet, for that matter, should try to produce something that pleases himself personally, not only when he's written it but a couple of weeks later. Then he should see if it pleases anyone else, by sending it to the kind of magazine he likes reading.
To start at a new place is always to feel incompetent & unwanted.
It is fatal to decide, intellectually, what good poetry is because you are then in honour bound to try to write it, instead of the poems that only you can write.
