Just like the title says. You can choose between two professions that pay fantastically, equally well: one which involves being very well known (star actor, musician, athlete, etc.), and one which does not. Assume that you’d enjoy the jobs themselves equally.
For the “fame” option, you don’t have to assume a Michael Jackson / Tom Hanks / Michael Jordan level of mega-fame where you can’t go anywhere without being mobbed, but you’ll be at least famous enough that, were you to walk around New York all afternoon without your hat/sunglasses, you’d almost certainly be recognized by several people, and chances are good that a couple of them would feel the need to talk to you. You also have to do your share of interviews, charity appearances, etc. OTOH, you’ll have the opportunity to supplement your income *somewhat *with your fame (i.e., from endorsements and the like), should you choose to do so.
