好记性不如烂笔头

好记性不如烂笔头:

Literally means:

a good memory is not as good as a worn nib.

Actually means:

No matter how good one's memory is, he or she will still forget something. So it is more reliable to write them down with a pen.

It is usually used to persuade somebody to write down things to remember so that he or she can browse it at any time and remember it clearly.

记忆力再好也有忘记的时候，不如用笔写下来可靠。

常用来劝人把必须记住的事情写下来，以便随时查阅，防止忘掉。
