Yes, you "acting as if" will be a change that noticed for sure.
As far as the believing what they say, I've read some real doozies (sp) around here that have been retracted or shown to be untrue, even if they're sure they mean it at the time. I know I've come up with some stunners myself in the past that make me cringe later. As such a repeat offender, I'm really glad I changed that unsavory habit.
I can see you learning & changing daily. Reading about it helps me to see things from a different vantage point too.
