This being the age of the internet, this can mean only one thing. I must immediately throw myself on the floor in a sobbing heap. Once I've had a good cry, I shall drink an inappropriate amount of whisky and send a semi-coherent rant to the editor demanding that they explain the caprices of their taste! Maybe head over to Twitter to passive-aggressively suggest that offending party is somehow not giving writers a fair shake. After all, I am a special goddamned snowflake who produces nothing but the finest in modern fiction.
At least, that seems to be the way I see some aspiring writers cope with rejection.
What's that you say, rational voice in my head? I should actually just get the hell over it, re-read the submission in question, identify its potential weaknesses and excise those flaws with the ruthless efficiency of an obsessive compulsive ninja?
Ye gods, it's as if I should cope with rejection of my work by embracing it as an opportunity to improve myself as a writer or something. Indeed, that is exactly what I shall do. Acceptance is a way to improve and enhance your career. Rejection is a way to improve and enhance your craft. The cycle continues as it must. I wouldn't have it any other way.
