For a long time now I have been drinking two cups of coffee in the morning. This has been fairly constant for a while. I remember long time ago used to drink much more, and throughout the day. At some point I hardly drank any. Then it settled to the mornings only.
I already drank only one cup at some point when staying at home and only the second one once I got to the office. Somehow that led to an assumption I need two cups, so I started having another cup as well at home when I was remoting.
Of course, now I haven't been at the office for a long time, still drinking the second cup. But do I really need it? I could just fine drop the second cup. The one I drank at the office was more of a social convention anyway, not due to minimum required amount of caffeine needed.
Besides some small savings over the years and perhaps some health benefits there is an actual reason why I started pondering my morning coffee rituals. It takes too much time to drink those two cups while waiting they cool down enough to be drinkable (I like my coffee black). Just a small improvement giving me few more minutes per day.
