Sometimes what you need to do is create a few extra calendars and fill every hour of the day with a label hinting at a purpose, a reason, a motivation: reasons to move from one moment to the next. Lunch. Dinner. Yard work. Computer stuff. Piano practice. Dog walk. You draw rectangles to block time. You think of the need for this as the kind of floor sweeping Buddhist monks do. To purify the mind, you must purify the environment, or in your case, time. You think: structured time is the only kind of purpose you have access to. It’s enough, you tell yourself.
