This is sound advice. My grandfather once told me that his father told him if you save your pennies, the dollars will take care of themselves. This essentially the 1920s or 1930s version of "stack sats".
I think it was nostr:npub1rtlqca8r6auyaw5n5h3l5422dm4sry5dzfee4696fqe8s6qgudks7djtfs who argued that bitcoiners and grandmothers basically give the same advice:
-Save money, go for walks, plant a garden, eat real food, don't trust the banks, focus on your community, get some sun, etc.
I think that comparison is under-marketed. We need some memes about it or something.

My grandmother always said that, too. To this day, I still roll coins LOL. It IS the modern version of “stack Sats”.
