A list of 25 Principles of Adult Behavior by John Perry Barlow

Concern yourself with what is right rather than who is right.

Never forget that, no matter how certain, you might be wrong.

Don’t badmouth: Assign responsibility, never blame. Say nothing behind another’s back you’d be unwilling to say, in exactly the same tone and language, to his face.

Avoid the pursuit of happiness. Seek to define your mission and pursue that.
