Yielding vs Obstinate
Obstinate people are inclined to search for new resources to achieve the goal. They consider each new situation from the point of view of improving the conditions for themselves, and having improved, they will fight in every possible way for their rights and privileges, without conceding an inch.
In an effort to "live better", Obstinate they often lose their sense of proportion, which is why they often remain at the "broken trough". Unable to win, they return to their original positions and strengthen them for the future.
Do not think that Obstinate - strong strong-willed personalities, and Yielding spineless opportunists. At the heart of this dichotomy is the principle of personal values. Victory is a relative thing. Obstinate simply do not tend to change their desires and a difficult goal may even become more attractive to them.
Yielding consider senseless principled movement towards the goal, if the goal itself is no longer attracted. We can say that for the Yielding the goal itself is important, and for the Obstinate - the way to achieve it.
