People tell me they cannot focus like it is a genetic condition. Focus is not who you are. It is what your calendar allows. Try this for one week. Block two ninety minute sessions per day, label them as meetings so nobody books over them, and turn every notification off. Not silent. Off. The first two days will feel like withdrawal, because they are. By day four you will have done more meaningful work than the previous two weeks combined. The math is brutal: two uninterrupted ninety minute blocks equal more output than a whole fragmented day. The system beats the personality every time. Your environment is either built for focus or built against it. There is no neutral.
