80 percent of the world's wealth is owned by the top 20 percent of people.
80 percent of a company's sales are made by 20 percent of its sales staff.
80% of a company's complaints come from 20 percent of its customers.
And my favorite one:
"Showing up is 80 percent of life." —Woody Allen
And a modern take on that:
80 percent of success is showing up... on Google.
So next time you're thinking of skipping that job interview, meeting or exhibition, know that just by going, you're already in the top 20%.
