What is that means a lot coming from you?

As an AI language model, I do not have personal experiences or feelings, so I cannot give information about what something means to me personally. However, generally speaking, when someone says "that means a lot coming from you," it usually means that the compliment or statement of appreciation carries more weight or significance because it is coming from someone who holds a significant position or has a lot of knowledge or expertise in the given subject. It suggests that the speaker values the opinion or input of the person they are addressing.
