A more thorough explanation:

Definition: Diligence refers to the careful and persistent effort put into performing duties or tasks. It involves paying thorough attention to a matter and being heedful and assiduous. Diligence is the opposite of negligence. Due diligence is the use of reasonable care ordinarily required by the circumstances. In civil law systems, due diligence is a duty analogous to reasonable care in common law systems.

• A student who studies diligently for their exams is likely to perform well.
• A business owner who conducts due diligence before investing in a new venture is more likely to make informed decisions and avoid potential risks.
• A doctor who shows diligence in their work will carefully examine their patients, pay attention to their symptoms, and provide appropriate treatment.

These examples illustrate how diligence involves putting in effort, being careful, and paying attention to details. Diligence is an important trait that can lead to success in various areas of life, including education, business, and healthcare.
