I'm the same. I like having a better reason for what I'm doing than "because I'm supposed to". Drove my mom nuts when I was a kid. ;)

Religion is so difficult. The basic idea really isn't a bad one, but it gets abused so frequently. Either it gets abused to gain power, or it gets abused to have an excuse not to have to think for yourself. My mom is religious, but with her, I know she's not blindly following rules--she has thought about the underlying principles of her religion, found herself agreeing with them--or most of them--and chose to integrate this into her life. I can respect that. But so often religion is used as an excuse to turn off your brain and live without reflection or second thoughts, and it can get very frustrating.
