Fascinating! This is very different from my own experience.

I believe in the "manage your energy" / Pomodoro techniques of regular breaks, so I might work for 25-50 minutes with consciously directed attention and then go read a blog to relax before working again. I am no disbeliever of conscious relaxation and breaks. I am a disbeliever in unconscious slipping of attention. If I let my attention slip to blogs or Reddit or comments during my chunks of work time, it tends to feed on itself and happen again and again and decrease my productivity, not restore my willpower.

YMMV. If your attention slips are self-correcting, then congratulations! Your mind has a feature that I envy.
