resignation letter, you should.
It is the perfect mix of humility and hubris. It explains why Groupon became such a phenomenal success and misguided underachiever.
His ability to pinpoint his own failings in this moment of self-reflection are admirable. It's refreshing to see him accept responsibility and know that his presence will only prevent Groupon from moving forward.
The lesson here is that great idea people are not always great leaders. And, sometimes the noise of "experts" can cause you to lose sight of what got you to where you are.
Good luck in your quest to lose that Groupon 40. Pritikin has worked well for a few of my friends. I look forward to seeing what you come up with next.
