A compliment about your work deserves thanks, not a list of reasons it should be smaller.

Deflecting praise feels modest and works like a correction. When someone says your work helped them and receives a list of its flaws, they learn that their judgment was mistaken and that offering it costs them something, so next time they say nothing. The habit also rehearses your own low estimate until it starts to sound like fact.

Try answering the next compliment with thanks and nothing else, even if that feels dishonest for a second. Let the silence after it stand. If you want to say more, ask which part was useful rather than explaining why it should not have been.
