Everything is prayer – not just what we normally think of as prayer. Everything we do is a transaction between us and God: every interaction between ourselves and another person – every member of our family, every coworker, every poor person. We make some prayer in every task, every job, every minute of the day, not just the ones we like or enjoy. This is how we can pray continually. 

But we, as humans, tend to divide the world into good and evil. This thing is God and this thing is not. But God created all. Who am I to say which things reflect him and which do not? The whole of creation is what he set in motion. That means that even when I am executing the most mundane task imaginable, I am praying.
