A few days ago, John Perry Barlow twetted a series of Adult Principles, and I enjoyed reading them. When he was asked where they came from, he said:
They're from a list I assembled for myself on the eve of my 30th birthday. Many years ago. This is the collected set from his twitter feed:
- Be patient. No matter what.
 
- Don't badmouth: Assign responsibility, not blame. Say nothing of another you wouldn't say to him.
 
- Never assume the motives of others are, to them, less noble than yours are to you.
 
- Expand your sense of the possible.
 
- Don't trouble yourself with matters you truly cannot change.
 
- Don't ask more of others than you can deliver yourself.
 
- Tolerate ambiguity.
 
- Laugh at yourself frequently.
 
- Concern yourself with what is right rather than who is right.
 
- Try not to forget that, no matter how certain, you might be wrong.
 
- Give up blood sports.
 
- Remember that your life belongs to others as well. Don't risk it frivolously.
 
- Never lie to anyone for any reason. (Lies of omission are sometimes exempt.)
 
- Learn the needs of those around you and respect them.
 
- Avoid the pursuit of happiness. Seek to define your mission and pursue that.
 
- Reduce your use of the first personal pronoun.
 
- Praise at least as often as you disparage.
 
- Admit your errors freely and quickly.
 
- Become less suspicious of joy.
 
- Understand humility.
 
- Remember that love forgives everything.
 
- Foster dignity.
 
- Live memorably.
 
- Love yourself.
 
- Endure.
