You are not what you own.
"Imagination will take you everywhere," said Albert Einstein, and he was right. As humans, we're limited in what we know and understand, but imagination transcends all of that.
Unfortunately, we tend to bolster our fantasies by buying the props that go with them. Francine Jay, author of The Joy of Less and Lightly, calls this "aspirational stuff." These are the things we buy to project a certain image, to impress others, or to help ourselves believe we're a certain type of person.
