It must be remembered that there is nothing more difficult to plan, 
more doubtful of success, nor more dangerous to managment than 
the creation of a new system. For the initiator has the enmity of all 
who would profit by the preservation of the old institution and merely 
lukewarm defenders in those who gain by the new ones.
    -Machiavelli
