Help to find a quote

Rating: Null/10 (15 May 2008)

I have been asked for a quote from Gandalf in Lord of the Rings to read at a wedding. Any appropriate quote would be welcome, but the one my son half remembers is where Gandalf is talking to Frodo reassuring him because he doubts he can fulfil the mission. He is saying something about 'it is not succeeding or failing but what you make of what you have', it is in the film. Sorry for vagueness, other quotes especially from Gandalf that would be appropriate would be great, hope someone can help, thanks v. much if you do.
Quotes I have used are Galadriel's words about the mission stands upon a knife, edge, stray but a little and it will fail. The other is from the Hobbit which I read umpteen times as a child, before the whole trilogy got popular, it was an unknown book almost, only printed once. It is the dying words of Thoring to the hobbit about 'Child of the kindly west, wisdom and humour blended in measure i if more were like you the world would be a merrier place, but merry or sad I must leave it now' it captured something nice about Englishness, and that is hard to find these days.
Vicky. Wedding is end of the May, my son's.
