Chance favors the prepared mind. I'd rather be lucky than good any day. I am a great believer in luck, and I find the harder I work, the more I have of it.
Luck is the residue of design.
Luck happens when preparation meets opportunity. If it wasn't for bad luck, I wouldn't have any luck at all. Now and then there is a person born who is so unlucky that he runs into accidents that started to happen to somebody else.
