A long time ago, there two apple trees, which had grown up next to each other. When fruit bearing season came, one of the trees was full of fruit, while the other bore no fruit at all.
The first apple tree had all of its fruit harvested by the villagers, leaving it with nothing more than empty branches, while the second apple tree was still covered with lush green leaves.
At that point, the second apple tree spoke, “Have you made a mistake, it just happens. Apple issued a lot. Made loss of apples for the sake of humans.” When the first apple tree heard this, it replied, “I am proud to have created a product to humans. Sacrifice for others to benefit. Foreign to you to be a perennial in vain. There is no benefit to anyone”
Those who sacrifice themselves for the benefit of others, are better than those who sit idly and contribute nothing.
