The Japanese secret to health and happiness: Ikigai. Ick-ee-guy, it’s a word you’ll be hearing quite often. Ikigai is a lifestyle concept that has been cannily co-opted by the publishing industry. It’s Japanese, and it means something like “purpose in life”, or “thing that you live for”, or “thing that gets you out of bed in the morning”.
The Happiness Equation promises to tell you how to “want nothing and do anything in order to have everything”.
Really, ikigai just codifies something we needed all along. The books won’t necessarily provide their readers with all-encompassing answers, but at the very least might guide them to a good question.
