Some of my acquaintances don't have breakfast. Some of them tell me that they do not have enough time to eat breakfast. As I see it, if that's the only reason for not having breakfast, they have only to get up a bit earlier. I wonder if they can work with their full strength without breakfast.
I sometimes can't eat lunch thanks to my work, but human beings need to have something before starting their work, don't they? As I take on long operations, my concentration wouldn't continue throughout if I don't have breakfast.
It might be unsolicited advice, but I often tell my subordinates to have breakfast. If it is not raining, I go for a short jog and take a shower in the morning before breakfast. That helps get the old juices flowing, and makes me feel ready to take on anything the day may throw at me. The following picture was from the net. It shows a typical Japanese breakfast.
