What do the statistics matter if I’m happy and have more than enough anyway?

Good news from tax accountant, I don’t need to make the December IRS payment because my income was cut in half from last year.  Really?  Shouldn’t I be squeaking then? Apparently everything else in my life accomodated and made it all work out because I’m living the same happy life. I haven’t looked at my profit and loss statements for years because I know the numbers don’t mean a thang.  My being happy is what counts. What do the numbers matter if I’m happy and have more than enough either way?
