Are you really going to sit there and state the obvious.
Why not just say 'Thank you ' without looking away, feeling foolish or any of the other 101 ways you have a negating a complement.
Someone has just given you a positive gift of their appreciation for who you are and what has got you to this point. By negating it you are slapping them in their face and letting it be known that they are not worth much in your opinion.
Rise to the occasion and smile too.
