Hard to concentrate. I worried incessantly about work. I’m not in a good physical state, am constantly tired, and my concentration is impaired by all the other things going on. Too many “building lots” in my life, as we say in Germany. I know that it’s a mistake to wait for the perfect day when I’ll be well-rested, unfazed by other problems looming around the next corner, and willing to write a paper less than perfect. Such a day won’t come. Need a different mind-set – any ordinary day can be THE DAY. Like, Tuesday. Nothing wrong with Tuesday.
