You aren’t obligated to stunt your personal growth in order to pacify another person’s yearning for a predictable existence. People who tell you not to change are being selfish.
People will tell you that your personal growth is pretentious. Their insecurity is surpassed only by their naivety. Change takes work, and new habits don’t come naturally. You might have to force it. There’s nothing inherently wrong with trying to be something you are not. Students become doctors. Caterpillars become butterflies. Metamorphosis isn’t wrong, but deception is. Life is the art of being a genuine fake.
