When life gets really hectic, and really crappy, and I feel like taking an automatic weapon to the guy tailgating me in traffic, the best thing I can do is PRAY.
I don't pray enough.
As a Christian, I believe that prayer should come as natural as breathing, but it doesn't. That's why I have found the British-based website re:Jesus helpful. It has a daily prayer that walks you through settling in, a brief reading from the Bible, and gives some practical tips on what to do after you pray. Check it out if you get the chance.
