Never be disloyal to who you are or what you need in order feel good, stay in the loop or keep friends.
Stay true to what you value and need in order to sustain and maintain the strong long-term foundation of who you are and who you are becoming. It gets difficult to decipher what has value or not in a world where it is easier to lie via social media.
Quite often changing opinions for others beliefs, following the current trend or conforming can be the worst disloyal behavior to self-growth. Don't allow yourself to change for the sake of others. Change because it's the right thing for you to do in that current moment. Change because you want to grow or because you know better.
Don't ever change because of someone else's opinion.
