Treat others as you would expect to be treated.

I had an interesting experience today. The driver of the vehicle in front of me decided to stop and have a conversation with the driver of the vehicle next to him, which also stopped. It did not seem to matter to either driver that they were holding up other people. For a split second, I consider sounding my horn and even getting out of my vehicle to go and have a word. Fortunately I was able to catch myself and decided to just sit patiently and wait. At this point I resolved to never knowingly put my time as more important than someone else's. Also, to practice being patient and not expect everyone to behave perfectly.
