“The most durable thing in writing is style, and style is the most valuable investment a writer can make with his time. It pays off slowly, your agent will sneer at it, your publisher will misunderstand it, and it will take people you have never heard of to convince them by slow degrees that the writer who puts his individual mark on the way he writes will always pay off.”
—Raymond Chandler (1888–1959)
“Thus I alone, where all my freedom grew,
In prison pine with bondage and restraint;
And with remembrance of the greater grief
To banish the less, I find my chief relief.”
—Henry Howard, Earl Of Surrey (1517?–1547)
