I can personally testify that praising God is an enormously boring activity, even if you're still young enough to truly believe in God.

To each eir own. Praying was actually pretty fun, given that I thought I was getting to talk to an all-powerful superbeing who was also my best friend. Think of Calvin talking to Hobbes.

As for group singing praising God, I loved that. Singing loudly and proudly with a large group of friends is probably what I miss most of all about Christianity.
