学习知识的过程就是“积少成多，滴水成流。”“积少成多”，汉语成语，指积累少量的东西，能成为巨大的数量。与英文谚语“many a little makes a mickle”意思相近，表示“many small amounts accumulate to make a large amount”。

例句：

巨大的财富起初是由少量的财富积累起来，正如积少成多，滴水成流的道理一样。

Huge fortune was accumulated from a little amount at primary stage, it has the same reason that many a little makes a mickle and many tiny drops accumulate to form a river.

甚至从小处节省下来的钱也能积少成多。

Even small savings can add up.
