Recently I had developed this real bad habit of reading things on my smartphone during breakfast (and lunch, too, often). This is really bad.
While the optimum is to simply eat during breakfast, and devote your attention to the food you're eating, that's too big a step in one time.
So for now, instead of smartphone, I do tsumego during breakfast. It's really fun and casual for some 10-15 minutes of L&D in the morning
