Every night there can be something new to learn, or a reminder of what was already learnt for your kid through the bed time stories. That was the best possible time when they are getting ready to be relaxed from the overhauling day (schooling and homeworking is always underrated). So, the last thing they cherish for that day can be a brief story that make them rejuvenate for the next day, and aid in becoming a better individual by next morning.
What if, they dreamt a vision from that story they just learnt, as a bonus. What if, they build their life around that morality they just cherished. That would be a huge bonus. Past accumulations of tiny chunks of gold was the only reason for the current goldmine.
