I think there is a lot of useful advice in here but it needs to be filtered against the cognitive biases of the author, who comes off as extremely obsessive and judgmental. These are useful traits to someone laser focused on controlling their own impulsive behavior but possibly not generally applicable to others in such an extreme sense.
I think him even hinting at it being bad triggered the rationalization behavior in you that he talked about in the article.
Hence why you just rationalized why you didn't need to listen to certain advice given in the article...
Coffee and orgasming is arguably not bad (there are health benefits to both). No one would dispute that the author’s kleptomania _is_ deviant behavior though. So I disagree that the goal should be to purge _all_ addictions, the goal should be to live a good life and eliminate addictions that obstruct this. The article still has good advice when viewed through this lens.
