Try Googling 10 Lessons In Business and see what you get.
I did, and in a fit of helpful generosity, Google spilled out about 281,000,000 results in 0.25 seconds. Lots of stuff of various usefulness or uselessness: lectures, seminars, articles, training, motivational speaking, quotations of business gurus, lessons for idiots, for CEOs and for dummies — you name it.
You wouldn’t find the One Big Joke below among the results of Google search… until such time as Google devours this post, indexes it and, eventually, spits it out as the result number 281,000,001. Watch out for a content that might be objectionable to your tastes. Use your own judgement and common sense.
