Who else has so many distinct parts of themselves that it feels like they are acting all day?

I have my childlike part, serious manager, performer, seducer, intellectual, etc. Each part tends to have different values, interests, emotions, and body language. 
I would make a great actress because I am great at playing the parts (I actually want to start acting again). Sometimes people are surprised by how easily I can change. It has turned off and scared people because of how much I can change.

Who else related?
