I stopped procrastinating as much and kept more organized. I also spent more overall time on productive activities.
The wearing off was just a slow gradient of falling back into my usual level of productivity. I didn’t notice it immediately as it was happening, only upon reflection.
I will attempt to do so but I have no way of knowing whether this is accurate or it is just the best rationalization my brain came up with. In addition, I know very little of psychology and my attempt at introspection is probably inadequate to give much useful information.
If I introspect while making a decision I can notice a succession of feelings in response to each other. I tried reflecting upon the experience of making a poor decision and explicitly noticing the affective factors that influenced my decision. I constructed a new feeling which I thought would promote productivity. I attempted to suppress thoughts supporting the poor decision while promoting my constructed feeling whenever I was making a decision related to productivity.
