To have a grievance is to have a purpose
in life. — Eric Hoffer
You are slow to complain. This is because you only complain when
you are very sure that you have a significant, valid grievance and that
pursuing it stands a reasonable chance of changing things for the better, from
your perspective. You seldom complain just to express displeasure, resentment,
or dissatisfaction. You complain because you want to change something and think
you will succeed. Complaints are, thus, proactive, not reactive.
