I strongly recommend two one-hour audios. Neither is directly about planning, start-ups, or business stories, but both are fun, extremely interesting, and really important. This is stuff you need to know.
If you're running a business, or you're starting a business, or you're teaching business, then you need to know about stress, dealing with stress, and stress-related diseases. And there's no better way than these two lectures by Dr. Robert Sapolsky, who teaches at Stanford University.
Ideally, get out of the office, take a walk, and plug into this. Each is a few minutes short of an hour:
- Why Zebras Don't Get Ulcers
- Stress and Coping: What Baboons Can Teach Us
