That's what akrasia means. That your actions differ from your spoken intentions in certain ways. In your example, the intentions are rational, the actions are not - in a particular pattern we call akrasia.

It comes down to what you identify with more as a "person". The fragment who acts? Or the fragment who talks about how they wish to act differently? And which fragment do you want to assist in making the other fragment be more like them - the intentions like the actions, or the other way around?
