If you are a beautiful strong black woman, someone will put this in your comments.

Exaggerate your emotions. If you watch anime or read manga, you will notice that many of the characters' reactions are pretty extreme. Take your desired personality's basic traits, and exaggerate them. If you want to be happy, act extra happy. If you want to be cold or serious, act extra cold or serious.
One of the most notable is Edward Elric from "Fullmetal Alchemist". He gets very upset whenever someone implies that he is short.
There are many emotionless archetypes as well. Instead of exaggerating your emotions, try concealing them and acting cool, calm, and collected.
