 Not submitting a resume sooner might mean that someone misses out on getting a new job, which in turn would lead to them earning more money and thus, someone who says that they do not regret not doing something sooner is actually contradicting themselves.
Consider the statement "I missed a chance to get a new job the other week and I really wish I had put my resume in sooner.". Is the statement "I do not regret not submitting my resume sooner and missing the chance to get a new job because who want to earn more money anyway?" false? Yes/no/unknown
