What a hard choice! In general, I'm pretty happy with my life and I don't feel the need to trade places with anyone. But if it's only for a day, that could be fun.
I thought of Lea Michelle - wouldn't it be incredible to be able to sing like she does? But then it might be very crushing to return to my real life without that awesome voice.
That's right, I'm picking Oprah. It could be all kinds of fun to be that powerful for a day. As Oprah I would make some book club picks for my favorite authors so that many others would read them too (and none of those depressing books that the real Oprah picks).
I would finally learn the truth about that whole Oprah/Gayle/Steadman situation.
I might go through the show lineup of the new OWN network and get rid of shows I don't like. I actually don't know any of the shows that are currently showing, but I'm sure there must be some I wouldn't like.
And finally, I would make a VERY generous monetary donation to a deserving family (I won't say who that family would be, but as a hint... S_ _ _ _ _S). And probably give them a new car. I really need a new car... ;)
