Considering you could have used the money to buy bitcoins and essentially double your money instead, what purchases did you make this year that you are now regretting?
If you knew what you know now, would you have been more frugal with your money?
People that think this way are never content. You make your choices and move on.
"Gee I could have bought bitcoin instead of this boat." robs you of the enjoyment of the boat and gains you nothing but regret.
Enjoy the boat.
