But what if I want a faster horse?

People overuse the original quote as an excuse to never listen to customers, but the real wisdom is to ask why they’re asking for a faster horse (to get around quicker) and see if you can think of a better way to meet that goal.

Overused and misattributed. What Ford actually said was: “If there is any one secret of success, it lies in the ability to get the other person’s point of view and see things from that person’s angle as well as from your own”

^ this guy knows Jobs To Be Done theory ;)

For those who don't, reading "Competing Against Luck" by Clayton Christensen will dramatically improve your ability to create successful products/services.
