Do you ever look back at yourself at different stages in your life and feel like it was a completely different person?

I just found some old hand written poetry from when I was 17 and read through almost all of it. I was shocked to see how different it was from the things I’m passionate about now. I also found a bunch of old letters from when I was 13 that even blew my mind more. I just want to hear everyone’s opinion on this since I keep thinking about it almost every other day.<br><br>Edit: thank you for the awards guys and to everyone who replied to this post!
