If you're worried about putting food on the table or putting a roof over your head, that stress is definitely will contribute to unhappiness, but once you have your basic needs met then incremental money.

What’s the best way to build a brand for the long term? In a word: culture.

If someone is self-aware, then they can always continue to grow. If they're not self-aware, I think it's harder for them to evolve or adapt beyond who they already are.

The biggest (and hardest) lesson I've learned in life is that the external world is just a reflection of the world within.

Ask yourself: would you be comfortable printing everything your employees, customers & partners have to say about your culture?

Usually my 'a-ha' moments are when I'm not trying to think of how to solve a particular problem.

I think maybe 50 years ago people and businesses felt like they had to choose between maximizing profits and making customers happy or making employees happy, and I think we're actually living in a special time where everyone's hyperconnected, whether through Twitter or blogs and so on. Information travels so quickly that it's actually possible to have it all, to make customers happy through customer service, to make employees happy through strong company cultures, and have that actually drive growth and profits.
