Taking gap years for art school before attending an ivy league

Since your sister went to Yale, would it be correct to assume that they donated enough to Yale to give you a substantial advantage in admission there, and that is the school they are pushing you to attend?

If so, would you be satisfied doing a major in art (probably the filmmaking concentration) at Yale and including the animation courses (7, 185a, 285b) and related courses?

Perhaps he is looking at the reality that art is a high-Gini line of work where a few successful artists have high earnings, but most struggle as “starving artists” or have to find other types of work to pay the bills. However, many people do go into general business type of jobs without having business degrees. If you do study art, you may want to take out-of-major courses in the various social studies and statistics, as these subjects may be applicable if you need to seek non-art jobs.
