鐵杵磨成針英語這么說？

鐵杵磨成針 Strokes fell great oaks,
Grinding It Out,perseverance will prevail
只要功夫深鐵杵磨成針 if you work hard enough, you can grind an iron rod into a needle

perseverance will prevail
[例句]只要功夫深，鐵杵磨成針。
With time and patience the leaf of the mulberry becomes satin.

譯法較多，達意即可，摘抄兩句如下：
if you work at it hard enough you can grind an iron rod into a needle.
Constant grinding can turn an iron rod into a needle.
