What's important is to imbibe the correct values from your religion and live by those values. It's not just about symbols and rituals only. I feel it's no use doing rituals right if you've not conducted your life according to the positive values religion teaches.
I believe one should not get fanatical about one's religion. It's good to be religious but not so fanatical that you lose respect for other humans.
Strength of character is more important than being deeply or overtly religious IMHO.
