in the late nineteenth century, p&g mainly sold candles.
but the company was in trouble due to the invention of the light bulb.
suddenly, candles seemed to become almost useless. the future of p&g seemed to be hopless,
but a surprising event saved the company. an employee forgot to turn a machine off while he went to lunch.
this created a strange material. the employee tried to find a use for the accidentally made material and turned it into a kind of soap. p&gnamed it ivory soap andsoap and made it the focus of their business. it was a great success.
the lesson here is that with a little creativity, a mistake can be a chance for success.
