Pulled a J. K. Rowling

You create your magnum opus early on in your potential career, however your utterly unable to ever create anything new that even comes close to the height your magnum opus has set the bar, so you settle down for a while and sit atop the pile of money that your magnum opus has made you for a few years until the percieved utter failure to live up to yourself causes your lonely ass to get bitter. So bitter in fact that you decide it's a great idea to take those feelings to social media and turn them loose on someone or something. You climb up on a soapbox you have no personal stake in climbing on top of nor any right to be on. You take this to a level in which your figurative or literal P.R. manager has a figurative heart attack and or quits and then you dig yourself into a hole so deep that the people who helped you bring your magnum opus to life in one way or another are no longer comfortable associating themselves or their work with you any longer. Not denying your part in it of course but no longer associating with you nonetheless. In the end you've succeeded in tarnishing your P.R., your livelihood, and what's left of your potential career for something you have no personal stake in, no real gain from, no real knowledge of, and no reason or right to tarnish your P.R. livelihood or your potential career over.
