The past two weeks have been busy for Kip Tindell, the Container Store's chairman and chief executive. On Oct. 6, the home organization retailer released its second quarter results, reporting earnings that missed analysts' expectations and lowering its sales forecast for the year. The next day, the stock tumbled 25 percent — the same day Tindell released his first book, Uncontainable , about how the Container Store runs its business.
