I think I would be "Felicity"
because I would be a lot happier and want to be known and remembered for bringing joy and satisfaction everywhere I went.
On second thought... maybe I would call myself "Bea" as in "Miss Bea Haven."
OH! OH! I got another one.... I would call myself "Nova," yes, I would become a dentist and call my self "Doctor Nova Caine!"
OK, OK, no more stupid puns. Seriously, I think "Felicity." Love the sound of that name, and the implication of someone who brings joy.
