Is a lack of desire to consume also a blessing?

I don't feel any joy from spending money,
and I have absolutely no desire to show off or try to define myself through the things I own.
No matter how much money I make, I don't think my daily lifestyle will change; I just see saving and investing as a means to live freely, and perhaps there is a certain pleasure in seeing the numbers in my bank account grow?
No matter how much I think about it, there is truly nothing I want to buy.
