Over the past few days I have started practicing an idea I read in Norman Vincent Peale's The Power of Positive Thinking. It's called "Shooting Blessings". In the book Peale describes the practice as something one of his colleagues practiced while traveling. It's very simple to do. As you go about your day you secretly "shoot" blessings to people you see out and about by saying a quick little prayer for them. You don't have to know them or anything about them, just wish them well. I've been using this practice as I drive to and from work every day as cars go by. This has been particularly helpful when I'm in a lot of traffic because it forces me to think positively about the other drivers rather than getting upset when I get cut off or someone doesn't use a turn signal. Praying for them instantly changes my mindset so when I get home my family doesn't have to deal with my travel frustrations. I'm amazed that something so simple can be so powerful.
Give it a try!
