Most friends judge each other like investments & never realize it. When someone stops being profitable they stop wanting them as a friend.

All people hide the bad parts of their personalities & bad people do it better. Your enemies & friends will sound exactly the same when you're around, but who's really your friend?

It's everything: it's their interests, hobbies, & loves - it benefits people to change their personality for everyone they know.

It's so hard to get intelligent advice that it's usually not worth asking - most politicians know nothing of history, most musicians know nothing of music, & most people know nothing of life. Really intelligence is just admitting what you don't know.

Never think "no one could be that bad" - millions of people make their livings lying as a salesman & CEOs, so how bad is any other lie that makes them money?

Everyone's "friends" are there when it's fun, but will they disappear when you need them?

There's a good chance that everyone you ever meet will somehow betray you.

And finally, the most obvious advice of all that *no one* in history has ever listened to:

_______________Don't try to change people.
_______________If you argue you're telling them who to pretend to be.
_______________Don't waste five minutes.
_______________If they think you're useful they'll lie to you for 90 years.
