The famous saying that effort is directly proportional to success.
Without bitterness, there is sweetness. Without the accumulation of every small step, a person can't walk a thousand miles. If you don't accumulate small streams, you won't be a river. Take one step, but not ten. After studying hard at the cold window for ten years, I came to be the first, bowing my head is the sea, and looking up is the future. I worked hard and became famous overnight. Study hard and make progress every day. Many a mickle makes a mickle. Water drops make an ocean.
