I don’t know it all, or even most of it. Each person has their own perspective and skills. Each live out of their personal repertoire of frugal hacks. Maya Angelou said when an old person dies it’s like losing a library. I would never have learned how to make good pie crust if it weren’t for Millie. Or attempt brewing dandelion wine if it weren’t for the check out guy at Sharp Shopper. Or see how to tie a knot on the end of a thread to mend something if it weren’t for Grandma. Old people know stuff. If nothing else they know the stupid things to avoid. But they know tons of valuable stuff too. What to keep and what to let go of. So ask questions, listen, apply, and grow.
The flip side is this. Frugality is not all there is. Younger people know stuff too. Our first born remembers how to get places when I’m disoriented. He can program the phone, do things on the computer (more than one way and without fuss or freaking out), and work the TV remote. Both sons tell me to lighten up and get perspective. Their optimism is encouraging, their dreams possible. Sometimes they have fun at the expense of work. And maybe, just maybe, that’s not too bad, to just enjoy life.
There’s always more out there to observe and master. And when your life is over, you hope you’ve done the best with what you have, and passed the good stuff on to others.
