There is a man who wants to cross the desert. The man is carrying a bag full of food and water. At first, he kept walking towards the north of the desert, but when he suddenly came out at night, he looked at the yellow sky and didn't know where to go.

There is a man who also wants to cross the desert. The man is carrying a bag with a compass in it. He thought he could get out of the desert that day, but the sandstorm blocked the man's trip. When the sandstorm stopped, it was the next morning. The man walked in the desert with one foot deep and one foot shallow. Until the next evening, he had not reached the center of the desert. Later, tired and hungry, I finally fainted on the third day.

There was a man, Ji Ji, who also crossed the desert. He has two bags, one with a compass, so he has a good sense of direction, and the other with food and water, so he is not hungry. At first, the man met a lost man in the desert, and he turned a blind eye. Then, I met the man who was lying on the sand dunes and dying because he didn't bring food or water. He also took a cold look and left. Later, he surpassed several people in need and ignored them. The next day, the man met a group of robbers, not only camels, but also two bags. Without a compass, the man walked blindly like the first man. Three days later, like the second man, he was starving to death.

The first of the three people got lost because he didn't have a compass. The second person can't go on living because of lack of enough food and water. The third man, although he has a compass and enough food and water, lacks love, so his ending is the most tragic.

A person's life is actually a trip. Starting from the starting point of life, you should take three bags, one for compass, one for food and water, and one for love.
