Pray Without Ceasing

In Revelations chapter 3 it mentions that we should pray without ceasing.  One thing I do have trouble with is getting mad at people for certain actions or behaviors that I myself do.  I once told someone that the things that drive us craziest in other people are the things we need to see in ourselves.
Anyhow, we don't have to be on our knees to pray, and when someone makes me mad and I want to say something sarcastic, etc, I've decided to quickly pray for that person and my relationship with them (not to mention my proclivities in the same area)
Pray without Ceasing!!!  Let God catch you before you fall.
