I will rate each set of confusing words as to their “distractibility,” that is, the degree to which readers will be distracted from the writers’ meaning if they fail to use the accurate word. Who cares? = *. Some people will be distracted = **. Many people will be distracted = ***. Usage problems distract readers from concentrating on meaning.
Question: What is the difference between "anxious" and "eager"?
Answer: "anxious" = uneasy, worried: "I was anxious about his safety."
"Eager" = enthusiastic for: "I was eager to hear the rest of his story."
Rating of Distractibility: **
