There was a time when I had to be concerned about the price of every purchase. When looking at a menu, my eyes would search for the lowest prices first, before making other considerations.

As I advanced financially, I got to where I didn't look at menu prices at all. Other purchases I might still consider shopping by "price first" though.

If I advanced financially even more, I could get to where I don't look at prices of more expensive purchases: cars, land, etc.
