Got my bonus yesterday. Spent hours salivating over toys that I emphatically do not need. A Tesla* (I don't currently own a car, but my god, if I was to own a car, I would want it to be a Tesla); a boat, even though I have never actually driven a boat; a TV as large as my wall; a new phone; a new computer; a house* (I currently rent).
I did this for a few hours (slow, slow, slow at work). I managed to avoid buying anything other than Vanguard TSM (which, of course, promptly declined on me yesterday and is declining today, too), but I have included this in the antimustachian wall because I completely understand the allure of "I HAVE MONEY. I WANT TO SPEND IT. SPEND IT ALL." I am nowhere close yet to the zen that most of the people around here have, where you don't feel like you're depriving yourselves by not spending gobs of money, and I'm envious.
*No, my bonus would not have paid for these things outright, but it was enough that it would have pushed me over the line on being able to "comfortably" buy one of these things (or, in the case of a house, lay down a down payment significantly in excess of 20%, or put a 20% downpayment on a ridiculously nice place) while still having a large amount of FU money.
