My real first thoughts: Use it to pay down your mortgage or other debt. Or, put it in the bank. Don't be in a hurry to spend the money. When I got bonuses, I always banked them for a year before spending. It's nice to have that peace of mind that the money is there for emergencies. Most of the time, after a year, the thrill had worn off and I wound up just saving the money to put toward my next house or whatever.

I'll take off my "parent" hat now, and answer your question. :)

$10,000 may not go as far as you think with a kitchen remodel. Your kitchen looks nice from what I see in the picture. The only thing I would change is the counter - and that's because personally I don't like tile counters. And a different window treatment would update everything pretty inexpensively. Unless there's a real reason to redo the whole kitchen, I think it would be a waste. So use some of the money for updates in the kitchen that you really need/want, but don't do it just for the sake of doing it.

Use some of the leftover money for your "awesome mancave". Again, don't go overboard, but do the things that will give you a real bang for your buck.

And bank the rest. (Sorry, couldn't resist! LOL) :)
