Summarised from Working for Happiness by Alex Frankel.

Over two years, journalist Alex Frenkel worked a diverse range of jobs to explore the connection between corporate culture and happiness at work – UPS, Starbucks, Gap, Enterprise and an Apple Store. He discovered three secrets to a happy workplace:

1. Go for flow

2. Foster authenticity

3. Find the right people

“…there is a moment when you are working at that place when you feel alive, when you are no longer questioning and thinking about life on the outside, life before the job, life after the job. In that moment, you are the job. It's a rare, elusive feeling, I discovered. But it's the secret to happiness at work.”
