Proper prayer is basically a form of meditation. It can take many forms, such as chanting, reciting, reflection, group prayers. Hence why Catholic and other classic prayers are so prevalent and powerful, there is a form of repetition in it with the goal of transcendence, it can put your mind at ease by concentrating on things that aren't your ideas and things like the Lord's Prayer remind you that you MAY get the things you need if you work hard and do things for others.
The prayer you learn as a JW however isn't that at all, it's a wish list for Santa basically, it is very self-centered and prayer as a form of meditation is actually eschewed. As a JW you pray for yourself, other JW's and for Armageddon to come and other such nonsense, it is totally debased.
Compare the phrase "Give us this day our daily bread, and forgive us our debts, as we also have forgiven our debtors." with any JW prayer you've ever heard from the stage. There is virtually nobody that ties your past actions towards your fellow person to the provision of the daily needs, you're not telling God in the Lord's Prayer that you need help forgiving another person, when the prayer starts, it's presumed you have already forgiven the person, only then can you ask for your own forgiveness and daily bread. It's an entirely different mindset than "please give me my food for the day, and help me overcome with the struggles I'm having with person x or y" - which is how the JW's teach you to pray, to ask for help without putting any action in yourself.
