They say, when opportunity knocks, open the door. But the only ones who knock on my door are mailmen and the Jehovah’s Witnesses.
Opportunity doesn’t knock, nor does it “come just like a thief in the night”. According to H. Jackson Brown, Jr.
Opportunity dances with those already on the dance floor.
which is often paraphrased as
Opportunity dances with those who are already on the dance floor.
According to Woody Allen
80% of success is showing up.
