annie, i'd love to dig in to some of the behaviora biases we face that interfere with our ability to quit. So if you think about am climbing everest, when we're thinking about trying to reach the summit, it causes this like miopia where we can't see like other things, other opportunities might have in our life. We tend not to see what we're giving up in terms of the other opportunities that might be available to us when we're on a particular path. And now we can see these forces like this is one of the big forces that causes us to not quit.
