"You can't expect people to be other than what they are."
And that's it. 90% of my frustration with the world dissipated. Now, this attitude is not the Russian Shrug which I hate so much, it is not saying "don't try to fix things because it's not worth the effort." It is that the simple act of working with what you have... not with what you wish you had, makes everything in life make so much more sense.
