A clean and tidy apartment where no one bothers me lol
Knowing that in the past, when I did have a chunk of money to spend freely, I chose not to take expensive vacations or buy a huge TV or designer clothes etc. because I didn't feel like I really wanted them. So now that I'm back to the beginning again, I feel rich because I'm free of envy for what other people might buy, because I know I value other things more.
Does that make sense? :)
Edited to add: I also feel rich right now, even though I'm actually money-poor, because I've finally gotten control of my spending habits. Even though I only had $41 in my bank account until payday today, at last I feel like I know where my money goes, and when I spend it, it goes places with purpose, not just leaking away because I have no control over myself. It's a great feeling to see that I've made so much progress with my issues with money over the last few years.
