I came across a page in an early edition of the Chinese 聖徒之聲 “Voice of the Saints” that has a well known quote by Heber J. Grant. I believe the quote is attributed to Ralph Waldo Emerson, but President Grant used the quote quite frequently.

“That which we persist in doing becomes easy to do; not because the nature of the thing has changed, but because our power to do it has increased.”
President Heber J. Grant

我們堅持去做一件事，這件事就會覺得更容易；並不是事的本質有什麼變化，而係因為我們做事的力量增加了。
