How do you reward yourself?

[Ryan Heywood]

I'm curious as to how other people here on BiggerPockets tie rewards into their investment process. For example, I'm a car guy and could spend way too much money if I don't keep myself in check. Assets before liabilities, right? So, I've challenged myself to first invest in 5 rental units before spending a cent on my next vehicle. Anyone else do something like this? I would love to hear about it.
