Limited willpower
It seems to us that we need willpower to get everything done in a timely manner. This is partly true, but the amount of self-control we are allotted for the day is not infinite.
Ignoring intrusive smartphone notifications and the brain's desire for distraction is only easy for the first few hours. Few people will be able to last in this mode until the evening. Self-discipline, work and all the little things you have to do during the day take up energy, and energy is limited.
How to counteract this: Get rid of temptations. Turn off all useless notifications on gadgets, keep annoyances at work to a minimum.
