Don’t listen to the others. What you are doing is good. I, too, am obsessed with a decent cup.
Just yesterday, I was out with my wife and we went to a coffee shop. I got a superlative cappuccino and picked up a pretty expensive bag of beans meant for espresso. So good.
When I was younger, I could never afford this sort of thing, but as I get older I can’t really enjoy a lot of other things and don’t need to spend much to live other than basic expenses. :)
