It seems to me as if it would (always) be better to behave defensively. It seems to me as if the thought of having to act, of having to plan, of being able to forecast cause and effect and thus (apparently) achieve planning certainty is one of the most momentous misconceptions of our minds.
Not offensively step forward – preventively, preemptively strike, act first, take the reins, shape „future“, … master – Not doing, but accepting, …resting, …standing, …looking, …bending, …recognizing, … flow along.
That seems to me to be the way to find happiness in life. Of course, such an attitude also means giving the biggest piece of the material cake to the others. If not the whole one.
But if we look around, we realize that it is not this cake that makes someone full of happiness. Otherwise, there would not be so many unhappy people who feed only on this food. If we think we are unhappy without this cake, it is merely the effect on our perception of a consumer-society norm from which we have not yet fully liberated ourselves. It is a momentous misjudgment of our mind.
