Every time you identify a pattern, or trend; whenever you can figure out at least 2 different ways to problem solve, and whenever you intervene to bring someone up to catch you are actually having a "Eureka" (Greek for "I got it/I found it) experience.
The EE is all about identifying, problem solving, and finding the answer. Some call it "getting a clue". So, all it takes is for you to have a very alert and fresh and flexible mind to look at situations from all (however many) angles. Your Eureka effect will certainly happen!
