[Max Goodman]

Succeeding as a poet means you know/you're nobody.

Nicely phrased. Meaning not only that there is little worldly success to be gained through poetry, but (probably among other possible meanings) that a poet's success lies in coming to terms with one's insignificance (an insignificance shared but maybe less-well understood by lawyers, political leaders, celebrities...).

I'm not a big fan of triolets, so grain of salt: I'm not sure the form is adding to that fine statement. Unless there are implications I'm missing, the repetends don't change meaning in significant ways.

FWIW.
