Some words of wisdom here from American writer Henry Miller (1891-1980). A controversial writer, several of his most characteristic works were banned in the US until 1961, and the publication of Yropic of Cancer led to a series of obscenity trials, the outcome of which became one of the more notable events of the “Sexual Revolution.”
No such controversy here, but rather some rules by which to conduct your writing life. The majority of them, I would argue, are easier said than done. But no one ever said that writing was easy.
