Your list seems very gardening focused. How about something like "reduce your monthly expenses by 10%", "invest in a local business", or "make a profit from a waste stream/product"...
I initially had things on the list about developing an ability to save a percentage of your net income every year... "be able to keep 30% of your net income after food, shelter, heating, and personal transportation costs are taken care of." then 50%, then 65%. However Paul brought up a good point. He was saying how that he really doesn't care how people spend their money, and doesn't want to get into this thing where we'd actually be looking into what you're making and spending just to fulfill a badge requirement.
I think we can all agree that being able to develop an ability to be super frugal is crazy important. I'd even say that it could even be the most important skill for the average startup farmer to have. However the logistics of checking that would be too difficult and too messy.
I think we could put it back on the list in the future as a suggested goal.
I think it would definitely be an attractive thing for people to put on their Permies resume- "not only am I making 50,000 dollars a year off of my permaculture business, but I run it so well that almost all of that money is pure profit."
I think I'd rather hire a guy who makes 50 grand a year and keeps almost all of it over a guy who makes 100 grand a year and has to spend most of that on overhead. However I don't think its something we could or should make a requirement out of.
I like your other ideas. I'll try and get back to the list to see how I can incorporate them. Or, you could come up with some tasks to add as well!
