I'm thinking a possible advantage of the necessity of "baby-stepping" -- setting smaller goals than simply going straight from total scarcity to total abundance -- is that it reinforces a belief that there is some distance between the two states, hence a "cushion". If it was too easy to make the full leap all at once, you would feel like there's not much between you and a return to poverty, and that would make you very fearful with your newfound wealth. You may achieve material abundance while still retaining a scarcity mindset.
The simple, man-on-the-street version of this is the old saying, "easy come, easy go". |
