I wouldn't want to be anybody but myself for the long term. However, I wouldn't mind doing some vacationing as somebody else. I'd like the ability to decide each night before bed if I want to wake up as myself, or as somebody else the next day. I wouldn't get to chose who, it would be selected for me at random, and I'd have to stick with it the whole day till I went to bed again. That way I could take all the things I've learned from living in so many other people's shoes into my own life.
