In the example that I gave, you brush your teeth, your mouth feels better right away. That works.
By contrast if you start working on your project now, next week you won't have a miserable all-nighter. That doesn't work. Just ask anyone in college if you doubt me.
That is why a monthly feedback cycle did not prove to be successful motivation here.
I wonder though, isn't forgoing small short-term rewards for greater long-term rewards a key aspect of escaping poverty? How can you condition that behavior with short-term rewards?
But well-off people that I know manage to forgo short-term rewards by having an internal counteracting short-term reward in line with the desired long-term reward. Maybe this is a teachable skill..?
No. Poverty is an extraordinarily complex problem. Its root cause isn't even fully agreed upon by those who have studied it. The example in your link is not even remotely comparable or analogous.
The problems that lead to poverty are another story. They are indeed complex. And any discussion of it is made harder by the fact that people superimpose their morality+politics on top of the discussion.
I don't even want to begin to tackle that...
...except in this case, poverty has been around for 1000s of years unsolved.
https://buildingpharmabrands.com/2013/05/27/the-ad-that-crea... is inspiring that way. It shows how people who could not be motivated to solve a well-known long-term problem, tooth decay, were successfully motivated to solve a short-term problem that they previously ignored - the fact that you wake up with film over your mouth that doesn't feel very good.
Long-term problems without good short-term feedback loops rewarding the proper behavior are hard, and will probably always be hard for humans. So rather than increasing the reward for the long-term issue, we need to find good short-term reinforcements for good behavior.
(Yeah, easier said than done...)
