Zig Ziglar taught me huge amounts about being a professional sales person and much more. I used to listen to cassettes of his speeches driving back and forth to work. It was a form of NLP personal training.
Only 5% of CEOs have a marketing background and many risk being disconnected from the rapidly changing desires of their consumers.
If I re-order Zig's quote it gives a powerful call to action to every leader and middle manager to focus outwards and less inwards.
"Help enough other people get what they want, and you can do everything in life you want."
