I couldn't have said it better myself

I completely agree with everything you just said, and you worded it perfectly. A: "Before we finish the meeting, I just want to thank my team for their tireless work. We couldn't have finished the project on time without them." B: "Thank you, Sarah. I couldn't have said it better myself." A: "We are just so thrilled that you two found each other, and we wish you a lifetime of happiness." B: "I couldn't have said it better myself. Here, here!" A: "You have been an invaluable resource and probably the best intern we've ever had." B: "As your direct supervisor, I completely agree, and I couldn't have said it better myself."
