There is that old lottery promo "you can't win if you don't play". There is this quote: "You miss one hundred percent of the shots you don't take. Even though there is only a 1-5% probably of scoring". There is the saying 9 times down 10 times up.
Getting lucky is a function of trying, as well. Saying you have to get "lucky" isn't about luck, it's about a mentality of keep at it.
