It's okay for you to try out other people, stretch your limits, test out a new character in a new plot in a new world. Just remember, you are who you are, and one day you will have to return to yourself. Yourself will remember your dances with other persona, the tricks you did, the thoughts that ran through your head. Just be careful to make sure you will be able to return in one piece, that the memories you have from being other people don't turn into nightmares. You may only be other people for a short time, but yourself is forever with you.
