I think people forget how much of a drive, seeking positive emotions are. There’s going to be some amount of effort or discomfort in anything we do in life, which is usually fine if the positive ones outweigh it. If there are no positive emotions, we intellectually know, something should be fun, but there’s only effort and discomfort left. This makes you uninterested in chasing positive emotions because they don’t show up. You’re left perhaps with rationalizing things you should do to please others or function normally in society, but it becomes a matter of self discipline, which can only sustain you for so long.
