Prayer is useless in reality. There is nothing that "happens" when you pray, other than within yourself (placebo effect) b/c you feel better (if you are some1 that believes in the power of such).

There is no God "listening" to you (and millions of others) on some secret supernatural frequency (that can only be reached when u clasp your hands together JUSSSST right and go down to your knees) waiting to cure your grandad of cancer - or help you pass a test - or keep u from getting a speeding ticket.

Spend your time doing some ACTUAL activity that will generate the outcome that you desire, like making sure your will is up to date... studying for your tests, and slowing the fuck down in the vincinity of cops running radar.
