Podcasts tend to be pretty conversational. I’m sure Obama didn’t put the thought into the comment that he puts into his speeches, where every word and every sentence is crafted. I just took it to mean that he had this diversity of experience with people he looked up to, and that helped him grow as a person. I personally didn’t have a lot of people growing up that I thought of as role models (not that my life was in any way bad, just that I didn’t tend to relate to people that way). So maybe the way I took it was slightly different than he meant it because of the differences in our experience of growing up, or maybe he was just trying to equate exposure to diverse people with the development of empathy, and did so in the way it worked him him. Hard to say.
