Why don’t successful people and organizations automatically become very successful? One important explanation is due to what I call “the clarity paradox,” which can be summed up in four predictable phases:
Phase 1: When we really have clarity of purpose, it leads to success. Phase 2: When we have success, it leads to more options and opportunities. Phase 3: When we have increased options and opportunities, it leads to diffused efforts. Phase 4: Diffused efforts undermine the very clarity that led to our success in the first place.
Curiously, and overstating the point in order to make it, success is a catalyst for failure.
