If you're talking about your moral compass, 100% agree. But in certain things there's always something new to learn every day.
I have changed my opinion greatly over the years as to what I believe to be right and wrong. My mind isn't set on any particular thing having to be a certain way. I can see now that some things I grew up believing to be right, weren't necessarily so.
I hope not! Always room and a need too to be able to change
I will say that it seems the older I get, the more difficult it is to sway my opinion.
I'm going to admit to a bit of stubborn. Although some say it's mule headed, but what do they know. :D
