In the essay "Small Water Drops and Big Waves", "Small water drops can fall through the stone, one is _ _, and the other is _ _." What should I fill in the horizontal post?

Small drops of water dripped from a hole to a stone. When the waves saw it, they asked the water drop, "Why did you fall through the stone with such a small force?" Small water droplets smiled and said, "There is nothing mysterious about it. It is the result of my perseverance. "

The waves nodded: "I see, as long as you have perseverance, you can break through the stone." Then, the waves boasted to the water droplets, "I don't know how many times better than you." I want to pierce a hole in all the stones on the shore. " After that, the waves rushed to the rocks on the shore again and again.

Decades have passed, and the stones on the shore have not been penetrated by the waves. The waves sighed and asked the little water drop, "I have been working continuously for decades, why didn't I succeed?" Xiao Shuizhu smiled again: "If you want to succeed, you should also set your goals and concentrate on one thing." *

Small water droplets have told everyone: this is nothing mysterious, it is the result of my perseverance (perseverance)

If you want to succeed, you must also determine your goal and concentrate on one thing. (Concentrate on experience and be more specialized)
