I had to post under the 'Excellent article as usual'.
I grew up in the 50s and 60s with affluent parents. So, I never really experienced the 'make do' part of life. Then I married young, we both had good jobs, and again no reason to make do. So, I never really learned how to live within the bounds of sustainable living, as you so astutely put it.
But now in my 50s and into my 60s I have discovered what is important, and it's not the newest car, or the most up to date cell phone. It's gardening with my granddaughter, and cooking with my grandson, which includes growing and harvesting veggies and herbs. Even though he makes me taste ghost peppers. It's weeding along with my sweet husband who falls asleep in the sun while laying there weeding.
I have found a lot of joy in planting berries among my flowers, so while I'm weeding I can pick wild strawberries, or blueberries.
Excellent article as always, Sharon!
