I’ve always wondered whether there’s a chicken-or-the-egg component to following your bliss. Does a person choose a path blindly, from mere interest, or is it because, at least to some extent, that path is already a path? Case in point: I have spent years in and around theatres because, after taking a drama class in middle school because I thought it would have less homework than an art class (an almost-random selection), I was asked to get up and do an improv, and discovered to my own amazement that I already had a certain innate flair for that sort of thing. From that moment a life has followed. By contrast, I’ve always been interested in learning to play an instrument, I’ve invested in a couple guitars, bought several lessons, but I have almost no innate ability and I keep failing because I can never get past how incredibly awful I am. I suspect that for Prof. Campbell and the others, “follow your bliss” is a recognition that we each have a certain destiny (or a small set of possible destinies), in the form of skills that are at least somewhat innate, and that that little bit of edge gets us past the frustrations of failure enough that true passion can then follow.
