To act 'diligently' means you're applying yourself with focused and persistent effort. It suggests a commitment to doing something carefully and thoroughly, not just rushing through it. Think of it as the opposite of being lazy or careless. It implies a dedicated work ethic and a desire to do your best. Imagine a student 'diligently' studying for an exam; they're not just skimming the material but diving deep. It is like a marathon runner training every day.
