How do you pray?
The first question, I suppose is: Do you pray?
Do you talk to God? How?
Does he listen? How do you know?
Everyone who begins to live the Christian life has notions about what prayer is and "am I doing it right?" If you are talking to God, you're doing it right.
Now, there are the professionals, the saints who developed systems, the ones who taught. And they have a lot to say about prayer and how to and what is good and what should be avoided. Reading can be helpful, but it's never as good as the real thing.
Talk to God.
