#8- Let someone ahead of you in line

It's probably a good idea to let someone ahead of you in line in the store and in the carline. When in a store I try to be aware if the person in back of me only has one item as opposed to the many I have and ask them to go ahead of me. It's the same thing when you see someone in their car trying to get back out into the street and no one is letting them in. Or even when someone has their turn signal on and is trying to switch lanes, why not let them in. I have found that this kindness is often repaid to me. Call it karma, situational awareness, or just doing what's right.
