You're limiting it to "I want to do something, I need reminders" but it also applies when you're trying to convince people to do something as well, such as sales or particular behavior in apps. I can't begin to count the number of times that someone ignores the level of motivation and requisite "ability," in most cases mental/time costs, in something like account creation on a site. A barrage of fields irrelevant to the actual necessities of account creation get shoved in because "we want marketing data" or some other idiocy because either they discount the barriers they're erecting or wildly overestimating the motivation.
