I grew up in an enormous, scientific, do-it-yourself household. We didn't have a TV in the house, but we did have books, music, experiments, stories, and countless negotiations. (Think "Captain Fantastic" in a town of 3200 people - yup, we were THOSE weirdos) Life is a great teacher if you're curious, exploratory, constantly learning (and not distracted by screens).
Honestly, lack of $$ was a great motivator and taught us how to be resourceful and proactive...to be a lemonade stand entrepreneur, to make jewelry, candles, and aromatherapy products, to develop gluten free recipes, to entertain ourselves with an 8mm camera we picked up at a garage sale. And this was waaaay before YouTube. If we wanted it, we figured out how to make it / trade it.
In my family the experts were the Finder, the Letter Writer, the Scary Storyteller, the Map Reader, the Challenger, the Mechanical Tinkerer, the Adopter of Strays, the Photographer/Historian, the Poet, the Performer. You probably have something similar with your family. When everyone has a specialty, bartering is practical, efficient, and makes great business sense. Bartering gives us all the opportunity to consult with the experts, and negotiate the exact thing you're looking for, rather than making do with a product or service that was packaged for the masses.
I'm a photographer, a writer, an enjoyer of music, a creator of compilations, silly songs and videos, a yogi, a chef, a feng shui-er, reflexologist, traveler, and professional brainstormer. I love to dive into something new, iron out the bugs, then pass onto others what worked for me. And I love to learn from others who are passionate experts in some field or skill that I don't have.
Have I mentioned that bartering rocks?!
