For some types of personalities, a simple to-do list is all that’s needed to keep things on track. They don’t need reminders; they check their notes on their own accord. They don’t like being bugged about stuff, so please get off their case already; they know what they’re doing. Others need a little more prodding, goading and hammering. Maybe they’re absent minded, incredibly busy, or just the type of worrier who sleeps with three alarm clocks set at five-minute increments.
