Hive account@scarletsnow , "A lazy person won't succeed in life and theirs a possibility that he will commit a crime to earn a good living but a hard working person will surely be successful in life and become rich someday."
Being a hard working person rather just makes it more likely to succeed compared to being a lazy one. I would not think it makes it certain.
