A living object lesson for entrepreneurs. That’s what Forbes columnist Steven Berglas is calling Charlie Sheen.

“With his foray into monology Charlie Sheen has become a living object lesson for entrepreneurs. In a matter of months he took a product, himself, responsible for the success of the #1 rated CBS-TV sitcom Two and a half Men, and destroyed the grip he had on a thriving customer base,” Berglas writes.

Of course, we know the story all too well. We also know how Sheen became an overnight social media sensation. Sheen is still making some news headlines by crashing Drew Carey’s improv show and heading out on his own tour. But his hit series Two and a Half Men, the series from which CBS fired him, ran for eight years and helped revive his celebrity. There's no gaurantee of winning as he goes out on his own with his new attitude.

But as Berglas sees it, Sheen imploded—and there’s lessons in it for entrepreneurs. What were those mistakes? I’d recommend reading Berglas’ column to get the full story, but here is the take away in a nutshell: Sheen violated Peter Drucker’s marketing laws.

Here are some quotes from Drucker to chew on:

  • “The aim of marketing is to know and understand the customer so well the product or service fits him and sells itself.”

  • “The leaders who work most effectively, it seems to me, never say 'I'. And that's not because they have trained themselves not to say 'I'. They don't think 'I'. They think 'we'; they think 'team'. They understand their job to be to make the team function. They accept responsibility and don't sidestep it, but 'we' gets the credit.... This is what creates trust, what enables you to get the task done.”

  • “Follow effective action with quiet reflection. From the quiet reflection will come even more effective action.”

  • “Making good decisions is a crucial skill at every level.”

  • “Rank does not confer privilege or give power. It imposes responsibility.”

  • “The entrepreneur always searches for change, responds to it, and exploits it as an opportunity.”
