“If you can’t be happy with a cup of coffee, you won’t be happy with a yacht.”
You can replace yacht with anything you like.
And you can replace coffee with your drink of choice, but don’t go any further.
This simple thought can serve as a powerful, daily reminder to be grateful for today, the present, and what we already have.
Note: I had trouble finding the source of this idea—I thought it was from Naval, but I believe it may be misattributed. Regardless, the idea is strong enough to stand on its own, even without a named author.
