^If you want to never forget something, picture an absurd
relationship between the two things. Violence, taboo thoughts,
blood, ridiculousness - all are things that can help. For
example, if you are always losing your pen, next time you put it
down, just as it lands, imagine it being stabbed through the
surface of the desk with blood spurting out of the desk as it
screams in pain.
Trust me: You'll REMEMBER where you left your pen.^
