When on the quest for self improvement, you will encounter a lot of enemies of progress. Sometimes they’ll come in the form of old friends telling you that you are acting different now and that you don't act the same way you used to but that shouldn't deter you from your quest to better yourself.
One of my favorite quotes is by H.G. Wells:
"Sometimes, you have to step outside of the person you've been and remember the person you were meant to be. The person you want to be. The person you are."
When you are trying to better yourself you will find that you might have to limit the time you spend with old friends or even cut them out altogether because they could potentially hinder you from becoming the best version of yourself. Yes they'll call you "Brand New" they might even call you fake but what you have to realize is that it's not a matter of being "Brand New" it's about being a "Better You"
How else are you going to be able to help others if you can't better yourself in the first place after all?
