I grew up Catholic, but then became Athiest in my early teens... then a friend introduced me to another religion, which I studied and experimented with. It gave me great insights about the workings of the universe. But I later decided that the religious aspects of this religion were .. well... just not for me, but the results I was receiving were contradicting half of the things I was being taught about this religion, in example about it's dieties. So for a while I stopped with the practices, and thought about how to go over them properly. Retrying something, in a different way, I got some positive results. Confirming some things about every religion, and denying alot of things about all of them... I've learned to put together the parts of each religion I've studied to find what I currently believe. That is to say, bits and pieces of every religion are true, while as the rest are all misunderstandings. If you look at all of the religions (even the lesser followed ones, and the ones that are no longer followed because the people died out) they all have things in common.
EDIT: Oh and once when I was in church when I was 7, It was my first time ever being at a church that sings, so when they completed the song, I started to clap. It was my natural reaction to a good performance, but everyone looked at me and someone said something about it. So I said "Why don't christians clap?" or something.
