Both Aumann and Schelling are top notch game theorists. Aumann's papers are tough. By contrast, Schelling has written some non-technical books. Go find them, especially The Strategy of Conflict.
Somehow I know what to answer the next time my wife complains to me why I don't like too many open options offered to me. ("You're strange. I thought economics is an art of choice. Why do you complain when I tell you that to go to Building X you can choose either way 1 or way 2 or way 3 or... so forth. You always want less options"). Now I know the answer. Schelling has taught us! It's the focal point that interests me. Too many similar options can blur my focal point. Yes, it's the... Schelling's Point.
