The little girl in that picture LOVED putting on a show for anyone who would watch and it turns out I never really changed much. Most of us have the majority of the personality we are going to have when we are young. According to VeryWellMind.com personality stays stable throughout most of your life with the exception of a few areas. You can see changes in your anxiety levels, friendliness, and your eagerness for new experiences. So, when you feel like you’re changing as you grow older it’s more your circumstances, where you place value in things around you, and who you interact with and not necessarily your personality. Sorry- you’re stuck that way.
