Sometimes, a lay person would approach the Buddha and ask a question, such as, "If I earn all of the money in the world, will she like me?" to which the Buddha would reply, "It does not further". As the answer would not further his ultimate purpose, which is to give. (The question frames the asker as a 'taker', or 'possessor', or 'manipulator', etc.).
Does the answer to the question, "What are the pitfalls to improvement?", further my purpose to improve?
