Local saying: Daig ang masipag ng maswerteng tamad (a lucky sloth is usually better off than a hard worker). Must be a terrible joke, but ultimately I believe hard work + opportunity = success.
However, if you had to pick only one, your saying would seem to hint that luck outweighs effort and that's a sentiment that has been pretty common through the years (former Yankees pitcher Lefty Gomez - "I'd rather be lucky than good.") I'm interested in seeing which of the two would be more desired if a single choice between the two was presented.
