I have a funny and illustrative story about abundance and scarcity mindsets. I used to work in an office that had just a few too few forks in the kitchen. Because of this, people hoarded forks, often forgetting they had one at their desk and taking a second one back. Even though there were only a few fewer forks than people, there was almost never a fork available in the kitchen.

One lunch hour I walked to the thrift store down the road, bought a bag of forks for three bucks, and put them in the kitchen. Once there were enough forks, people stopped hoarding and we had more forks than we could ever need. It's about as clear an illustration of scarcity vs abundance mindset I've ever seen.
