For example, once you leave the room, you want them to say more than anything, "He/She was _____."
What would that one thing be?
After thinking hard about this, I was surprised to realize that mine is "funny". I want people to think I'm funny more than anything else. More than intelligent. More than sensitive. More than musical.
I want to be a clown. I want to make you laugh.
What's your thing?
