What exactly is your benchmark for being "rational"? If you mean becoming more openly critical in situations where your agreeableness prevents you from it, you should be aware that there are topics much more dangerous than religion where an uncompromising quest for truth might lead you to clash with the respectable opinion, both public and private.

That is not what I meant. I have no intention in becoming more hostile to religion; I'm having fun with it at the moment. My main issues are a) right now it doesn't feel like it hurts much to change my mind, meaning I'm probably not really changing my mind and I need to learn how to do it better, and b) my current schema for living life is deeply flawed. I care way too much about what others think of me, I've unthinkingly absorbed a ton of social conventions that I wish I hadn't, and my inability to say no means that I'm overbooked and exhausted all the time. Also I behave very irrationally when it comes to romantic relationships, but that's another story. And I'm a workaholic, though I would really be happier and get more done that I care about if I was able to work a little bit less.
