This is something I discovered by accident over the last decade. At first I spent most of my income. After normal expenses I would spend what's left over on entertainment and status symbols like newer cars, etc.

Eventually I discovered that I have no real desire or need to spend more than $1500-1800 a month. That's probably very cheap to those living in silicon valley but I'm in the midwest and earn more than triple that amount after taxes.

Watching savings pile up is satisfying for a while, but eventually I had to come to terms with what I'd like to achieve in my professional and personal life, aside from money. I'm currently going back to school and it's the best decision I ever made.
