You mentioned that your personality is fluid and you change it accordingly as needed, how do you do this?

In my childhood, I realized that "I am not my personality".

Because I could easily change my Mindset, Personality, Voice...

Because I just kept silent and looked, I learnt so many personalities.

Once you learn deeply, you can change your Mindset, Personality...

That's one way to truly realize that you are not your personality.

But if you do "Personality Development", then you'll be a stone of a personality and you'll keep yourself in an illusion that you are your personality.
