This is an interesting thread you've started Justine, and everything you say applies. I don't even feel as if I am the same person at all that I was about ten years ago and still keep changing so much and so quickly everyday.
In addition to what you've already said I'll mention a few because there are so many.
One thing is that I don't get upset in the least if someone has a different opinion or belief than I do. Anyone is just as entitled to there opinions as anyone else.
I can identify or have empathy with others in a way that didn't used to be there as much.
Selfishness has practically dwindled away in the sense that getting ahead, getting richer, keeping up with the Jones and wearing the latest fashion seems silly to me now.
It's early and so I may think of more later, but gosh, there are so many changes.
