Stubborn or Obstinate
Stubbornness has its kin…. focus, hard work, commitment, perseverance, persistence, never-say-die attitude, inner strength, courage of conviction, defiance of tiresomeness, lack of complacency, absolute zeal to succeed… to get things done… and to do it come what may….
Obstinacy has its kin…. disobedience, non-cooperation, a devil-may-care attitude, fierce unwillingness to oblige….
Both words represent the same trait in general… it’s where you apply these traits that define your character….
It really boils down to choice and free-will…. the stubbornness of “I will because I want to” OR… the obstinacy of “I will not because you want me to”….
