Facebook's board somehow distilled a hugely successful strategy from threadbare briefings by CEO Mark Zuckerberg, who explains in this video how he would scrawl all the board's Facebook news on a single sheet of yellow paper.

"Our directors still say, 'I love that single piece of paper with the summary of what's going on,'" Zuckerberg tells Fast Company for the magazine's "30-second MBA" video series. The lesson: When the numbers say you're working hard and making everyone rich, you don't have to worry about looking like a chillaxing slacker.
