Final thoughts...

I've been thinking about this paradigm-shifting stuff.  And what I really know or don’t know, and why, and how it has all changed over time.  Have I gone through any paradigm shifts?  I don't recall any specific monumental "aha" moments, but things have changed.  As a kid, I was very idealistic, and very naïve.  I believed that almost everyone was good and had enormous potential, that "right" should and would triumph, and I believed in absolute truths.  There was a certain way things should be done and that most people saw it the same way that I did.  Now, I view the world a mass of widely differing opinions and I define "truth" and "knowledge" as the specific principles or ideas I've made a personal commitment to, rather than universal constructs.  I am still naively optimistic.  I am wondering if anyone else has noticed any major changes?  Of if you have your own definition of truth, or reason(s) for believing in your knowledge?  It would be nice to get final thoughts from people.
