Do you think anyone is capable of “changing”?

Looking back in my life, I’m not the same man I was when I was say in my early 20’s


I was overall a more carefree and happy man then.


Nowadays I’m more stern and serious (maybe being in the marines played a role in that) but I digress. I have been told I don’t smile as much anymore.


To the question, if someone tells you “they changed” do you buy it immediately or are you more skeptical?
