Hi, I'm new. I'm studying Objectivism by following the reading list at http://www.aynrand.org/site/PageServer?pag...ctivism_sugread - I am currently at number 20. Just to let you know where I'm at. However, I haven't yet understood by which method and based on which values man chooses, for instance, which color to paint his house, which flavour of ice cream to like, which branch of a rational career to choose (both an engineer and a philosopher can have a rational career, but what makes man choose between the two), etc.? Does Objectivism tell us anything about this kind of personal tastes and interests - none of which seem any more or less rational than the other?
