Go hunting or foraging for food. You may need to invest in gear and permits, but if you already have these, this is an inexpensive way to get your own food. If you're ethically against the killing of animals, it's pretty easy to forage for food, depending on where you live. Just make sure to forage only for food whose origin and properties you are sure of. Getting sick or poisoned is never any fun.
Jeff have you ever considered adding something on price comparison sites for selling your used stuff? One of the fastest 100 bucks I have made so far was just from old textbooks and dvds on price comparison sites that give you the best offers. I know Bonavendi.com is a good but im sure there are others. Anyway would be interesting to see your take on the matter, the other ideas I found really creative though. Thanks for the read brother
However, this can be debilitating, to say the least. That's likely why we see so many get-rich-quick schemes and fad weight-loss diets. We want what we want and we want it now. But we can't expect that if we're serious about making a mark in business or society. Instead of instant gratification, in order to create sheer abundance, we have to do the most amount of work for the least initial return. We have to deliver massive amounts of value, and do so repeatedly. Plain and simple.

Don't put all your trust in Social Security. While it's a good bet that Social Security will continue to work for the next 20 or so years, some data suggest that if Congress doesn't radically alter the system — either by raising taxes or reducing benefits — Social Security won't be available in its current form. It is probable, however, that Congress will act to "fix" Social Security. In any event, Social Security was never designed to be the only resource for retirees in their later years. That makes it all the more important that you save and invest for the future. 
As an Instacart personal grocery shopper, you will actually be doing the grocery shopping yourself (so don’t crush anyone’s avocados!).
