It took him several minutes to understand any new idea  put  to  him,
and  this is a very valuable trait in a leader, because anything any-
one is still trying to explain to you after two minutes  is  probably
important  and anything they give up after a mere minute or so is al-
most certainly something they shouldn't have been bothering you  with
in the first place.                   - Terry Pratchett, _Reaper Man_
