Christopher Carfi shares an interesting Warren Buffett quote in this post titled, In Search of Failure:

 "I often felt there might be more to be gained by studying business failures than business successes. In my business, we try to study where people go astray, and why things don't work...Albert Einstein said 'Invert, always invert, in mathematics and physics,' and it's a very good idea in business, too. Start out with failure, and then engineer its removal." - Warren Buffett

So, seek out what is broken, figure out why it broke, and go fix it.  Excellent advice.
