This treasure is from Ben Rich's book Skunkworks.
Ben told Kelly about his plan to attend a 13-week advance program at Harvard Business School, which was only available to 150 carefully selected executives. Kelly wrote Ben a glowing recommendation, but still insisted that it would be a complete waste of Ben’s time.
"I’ll teach you all you need to know about running a company in one afternoon, and we’ll both go home early to boot. You don’t need Harvard to teach you that it’s more important to listen than to talk. You can get straight As from all your Harvard profs, but you’ll never make the grade unless you’re decisive: even a timely wrong decision is better than no decision. The final thing you need to know is don’t half-heartedly wound problems – kill them dead. That’s all there is to it. Now you can run this (excerpt) place. Now, go home and pour yourself a drink."
After Ben completed the program and returned to Skunk Works, Kelly asked him for his appraisal of the Harvard Business School. Ben wrote the equation: 2/3 of HBS = BS .
