I can relate to this really well. I think we've all think "this is me, I can't change" but change is constant in human , we changed based on our experience everyday and when we get more occupied with things we never even dreamt of doing , I think it changed out perspective too. So, I don't think we can have a perfect version of ourselves , we are bound to change at anytime. Nowadays too I found myself wanting to connect with people more which was what I hate doing then .
