From a slide deck about culture at Netflix:

You say what you think even if it is controversial

You are tenacious

You are quick to admit mistakes

It's about effectiveness -- not effort

Need a culture that avoids the rigidity, politics, mediocrity, and complacency that infects most organizations as they grow

Paul Graham:

It will always suck to work for large organizations, and the larger the organization, the more it will suck.

Donald Rumsfeld:

If you are not criticized, you may not be doing much.

Ira Glass:

Not enough gets said about the importance of abandoning crap.

If you're not failing all the time, you're not creating a situation where you can get super-lucky.

Benjamin Franklin:

It was about this time I conceived the bold and arduous project of arriving at moral perfection.
