Many people in this world think why should you pray? Is there a god? Well I cannot comment on if there is a god and if he listens to your prayers. But I certainly would say we must pray. Now you might question me if there is no god then why should we pray? Who is listening to our prayers? The answer is you are listening to the prayers. The vibration of sounds in each prayer helps open your senses and helps you think, what someone else could not think.
Well if you pray everyday like a routine, it helps discipline your mind. Its like going to the gym everyday it disciplines your body and you become fit. The same way praying disciplines the mind. A disciplined mind helps you control your thoughts, which in turn lets you think clearly. If you are in control of your thoughts, you will remain more calm and will be able to take the right decisions and create the right life for your self. This eventually will lead to a life you wanted, which will make your life a Happy Life.
