Sports and Rap star. Hey, Shaq's living my dream. Seriously, to have an empire of many high end boutiques (e.g. to own Bergdorfs, Barneys, Wilkes Bashford, Louis Boston, 10 Corso Como, Maxfield, Jeffrey NYC, Atrium NYC, Colette) as well the major department and specialty stores (from Macys to Robinson May to Saks to the Gap to Banana Republic) catering to pretty much every demographic, so I could dictate my style on the world. I would also own all the cool bars and make sure no own looking lame was allowed in anywhere, further consolidating my position as fashion tsar. I would also do science on the side, unencumbered by the need to write grants and do boring but payday science - just do whatever research I found interesting. Sort of like a more fashionable Howard Hughes.
