I'm still really happy with buying a massage cushion (not this one but about this type and price). I bought it shortly after I got my first job, and wanted one, noticed it wasn't too expensive (per massage), and went for it.

It's a nice treat that still feels luxurious and indulgent, so I also desire other indulgent things less.

Plus, I named mine "Adulthood" since I could buy it because I was an adult and my money was mine to do with as I wished. Thus my roommates and I were prone to say things like:

"I never dreamed Adulthood would be so wonderful"
"Sometimes Adulthood is all that keeps me going"
