I can see my work as a job. I do it for money. I likely already look forward to the weekend on Thursdays. And I probably will need a hobby as a leveling mechanism. In a career, I'm definitely more engaged. But at the same time, there will be periods when I think, 'Is all that really hard work really worth my while?'

U.K. psychologist Daniel Nettle thinks of happiness as a carrot on a stick, designed by evolution to show the right way, and also designed so that we will never permanently reach it. We likely would just sit around and eat sweet and fatty foods all day, and that is simply not in the interest of evolution.

Startups need to focus on building a foundation for their company culture early, and then they need to revisit it often. Every time a hire is made, a feature is launched, a Facebook status is updated, a press interview is given, a round of financing is raised, or a meeting is held, culture should be part of the decision-making process.
