Good for you--I mean that. My addictive superstimulus is learning new things with no practical relevance my work, like orbital mechanics or calendrical calculations. When I catch myself going on extended binges, I try to extricate myself by consciously directing my time and energy elsewhere. But it would be silly of me to indict textbooks as harmful objects. Any hardcore procrastinator knows that the focus is incidental and essentially arbitrary.
