"Success is simply a matter of luck" suggests that some attribute success solely to luck or fortunate circumstances. It implies that external factors beyond one's control play a significant role in determining outcomes.
"Just ask any failure" contrasts the notion of luck with the experiences of those who haven't achieved their desired goals. It implies that those who haven't succeeded might attribute their lack of success to bad luck or unfavorable situations.
In essence, this statement raises questions about the role of luck in success and the various factors that contribute to outcomes. It underscores that while luck may play a role, determination, effort, and other factors are also influential in achieving goals.
