“Winners have parties, losers have meetings” has been a motto (since at least 2001) of Sam Chisholm, a media executive in Australia and the United Kingdom. Meetings are often held be executives who are afraid of making decisions, while losers don’t have parties.
 
British businessman Philip Green has said (since at least 2007), “Successful companies have parties. Unsuccessful ones have meetings.”

Former BSkyB chief Chisholm heads for London and its ‘amazing’ television

Half a world away in Australia, Sam Chisholm is missing London. He misses his Hyde Park apartment, his local boozer, the Enterprise, and Langan’s Brasserie. He misses Tottenham Hotspur football club, of which he was a director. The TV executive misses English humour and manners. Not least, he misses the broadcasting. “British broadcasting is amazing,” he sighs.

The purse-strings are tighter at the network these days but Chisholm’s notoriously hard-nosed ways haven’t changed. “Winners have parties, losers have meetings”, and “To err is human, to forgive is not my policy” are just two memorable Chisholm aphorisms.
