Feeling the urge to buy something to reward myself but not sure what

I feel a bit stupid writing this out since it's pretty illogical, but I'm feeling an urge to buy something expensive since my business is doing well, and I'm on track to hit all of my financial goals. (FWIW, my net worth went from around $4m to almost $7m in the last year, and I expect to make $500k-$1m/year for the next 5-10 years. Our spending is about $250k/year.)

I've been doing a lot of expensive travel which has been fun, but I kind of want something tangible. I was looking at expensive watches, but I already own a few decent (not crazy expensive) watches that I don't wear. I was thinking of upgrading my car, but I work from home and really don't drive that much. (About 6500 miles/year.) My home has already been fully remodeled so there's really nothing I can think of to upgrade there.

I realize I probably shouldn't splurge on anything I really don't need so I'm probably going to wait the feeling out, but out of curiosity what are some things you've splurged on to reward yourself?
