Let’s add context first to keep things under control. I am talking about how one reaches to the Eureka moment or that Aha-feeling.
A blink is an expert intuition. You get this intuition when you are doing the same thing again and again and are able to look at a problem and relate it to the solution based on your expertise. Flash on the other hand is strategic intuition. This is the intuition you develop when you are able to connect the dots.
How can you develop the power of blink? From one Malcolm Gladwell’s book (Blink) to the other (Outliers), by becoming an expert. Gladwell explains it as the rule of 10,000 hours. You put 10,000 hours or 10 years into something to become the absolute expert in that. And then when you look at a problem in your space , you get a blink that directs you towards the solution. It’s that blink that tells you that you have what it takes to do it.
Flash or strategic intuition is essentially connecting the dots. You develop the power of flash by studying the history and having a presence of mind, both of which together will help you connect the dots and find the solution to the problem. The idea is to correlate what is happening currently with something that happened in the past. It is easier said than done because the most crucial thing here is a strong presence of mind to draw the correlation. But if you are able to do that, it shows you the way to do what is otherwise not possible.
Are blink and flash mutually exclusive? I believe they are not. They are in fact tightly related to each other and the best decisions are made when you apply both expert and strategic intuition together. The reason being, you often make decisions in the area of your expertise. In making those decisions when you think intuitively, you subconsciously use a combination of strategic and expert intuition. You draw from your expertise and with a strong presence of mind are able to connect the dots using examples from history. That’s when you reach the Eureka moment and go on to do something great and inspirational!
