A few years ago, I came up with a way to study people's happiness moment to moment as they're going about their daily lives on a massive scale all over the world, something we'd never been able to do before. Called trackyourhappiness.org, it uses the iPhone to monitor people's happiness in real time.
Prije nekoliko godina otkrio sam način kako proučavati ljudsku sreću od trenutka do trenutka svakog dana na vrlo velikom području, širom svijeta. To nikad prije nismo mogli. Zove se trackyourhappiness.org i koristi iPhone za praćenje ljudske sreće u stvarnom vremenu.
