How Much Should We Pray?

If you were in a room full of money and were told we could have as much as we wanted, how much effort would we make in collecting it? Would we work for five minutes then stop satisfied we had "done our bit for the day." Or would we complain about the lack of air conditioning as we pick up money. Or would we complain that "it's boring picking up all this money." Prayer holds higher value to us that money does, and yet we seem to not be aware of the value of the currency of heaven. How much should we pray? The answer is, as much as possible.
