The quality of being dogged; persistent determination, stubbornness, or refusal to give up in the face of obstacles.
From 'dogged' (adjective) + '-ness' (English suffix forming abstract nouns). The chain follows: 'dog' (noun) → 'dogged' (adjective, meaning dog-like) → 'doggedness' (the quality itself).
Throughout history, successful people often credit 'doggedness' as their superpower—not genius, but the sheer stubborn refusal to quit when everyone else said their idea was impossible, which is possibly why we compare it to dogs at all.
