I'm not sure we have the same definition of boredom: I can't be bored when left to my own thoughts without external stimuli (which is precious time, you need to allow yourself to have time to "do nothing", otherwise you're only ever reacting to events), on the contrary. The only time I can experience the brain-dead zombie state that is boredom is when I have to pay attention to a mind-numbingly inefficient task I am powerless to improve, like passively listening for hours to an auditorium university lecture that makes the mind rebel against the inefficiency (despite I love learning, but using other means). Frustration seems more like one that stimulates creativity as it motivates to find workarounds or new directions.
