Frustration and resignation are two sides of the same coin. Both are bad. Fustration, because it indicates that one is applying too much force, and resignation, because it indicates one is applying too little force.
The good option is the one in between the two: applying just the right amount of force to your actions, meaning, not too much and not too little.
People who are incapable of such moderation, of such interpolation, only see two options, the extremes of frustration and resignation.
They are hedonists whose judgment is reduced to binary choice between frustration and resignation, or in plain terms, between pleasure and pain.
If these were the only choices you had, which one would you choose? Pleasure/resignation, of course.
And if you came across people who didn’t choose the same option that you did, what would you think of them? You would think they are frustrated.
Why? Because that’s the range of your experience. You cannot see beyond that. You can only imagine crude movements of frustration and resignation. You cannot imagine, because you cannot perform, subtle, refined, barely visible, micro-movements.
But from my point of view, and I believe from the point of view of every individual whose judgment is beyond pleasure and pain, the ones who frustrate themselves are considered more noble than the ones who resign, for the simple reason that they keep struggling.
