I can't remember who it was, but I saw a comedy routine where the guy described a conversation he had with his financial advisor. The advisor asked him "What does financial stability mean to you?" The comedian, having just recently started earning real money from comedy for the first time, had never even considered such a question before and had to ponder on it for a moment. Finally he thought up an answer. "What financial stability means to me is when I'm ordering food and they ask if I want to add guacamole, I don't have to think about it, I can just say yes."
That line really stuck with me, and I have found it to be an accurate indicator of my own financial stability. Only works if you actually like guac though.
