“Difficulty attracts the characterful man, for it is by grasping it that he fulfils himself.”
La difficulté attire l'homme de caractère, car c'est en l'étreignant qu'il se réalise lui-même.

“Love always brings difficulties, that is true, but the good side of it is that it gives energy.”
In his letter to Theo, from Nuenen, c. 9 March 1884, http://www.webexhibits.org/vangogh/letter/14/359.htm
1880s, 1884
Context: Love always brings difficulties, that is true, but the good side of it is that it gives energy.... I have not yet had enough experience with women. What we were taught about them in our youth is quite wrong, that is sure, it was quite contrary to nature, and one must try to learn from experience. It would be very pleasant if everybody were good, and the world were good, etc. - yes - but it seems to me that we see more and more that we are not good, no more than the world in general, of which we are an atom - and the world no more good than we are. One may try one's best, or act carelessly, the result is always different from what one really wanted. But whether the result be better or worse, fortunate or unfortunate, it is better to do something than to do nothing. If only one is wary of becoming a prim, self-righteous prig - as Uncle Vincent calls it - one may be even as good as one likes.

"I create gods all the time - now I think one might exist" (2008)
Context: There is a rumour going around that I have found God. I think this is unlikely because I have enough difficulty finding my keys, and there is empirical evidence that they exist.
But it is true that in an interview I gave recently I did describe a sudden, distinct feeling I had one hectic day that everything I was doing was right and things were happening as they should.
It seemed like the memory of a voice and it came wrapped in its own brief little bubble of tranquillity. I'm not used to this.
As a fantasy writer I create fresh gods and philosophies almost with every new book … But since contracting Alzheimer's disease I have spent my long winter walks trying to work out what it is that I really, if anything, believe.

Quotations from Chairman Mao Zedong (The Little Red Book)

Introduction; part of this has sometimes been paraphrased : Our civilization has not yet fully recovered from the shock of its birth — the transition from the tribal or 'closed society', with its submission to magical forces, to the 'open society' which sets free the critical powers of man.

In his letter to Theo, The Hague, 11 March 1883, http://www.webexhibits.org/vangogh/letter/12/274.htm?qp=art.material,as translated by Johanna van Gogh-Bonger, edited by Robert Harrison, in The Complete Letters of Vincent van Gogh (1991)
1880s, 1883
Context: It constantly remains a source of disappointment to me that my drawings are not yet what I want them to be. The difficulties are indeed numerous and great, and cannot be overcome at once. To make progress is a kind of miner’s work; it doesn’t advance as quickly as one would like, and as others also expect, but as one stands before such a task, the basic necessities are patience and faithfulness. In fact, I do not think much about the difficulties, because if one thought of them too much one would get stunned or disturbed.
A weaver who has to direct and to interweave a great many little threads has no time to philosophize about it, but rather he is so absorbed in his work that he doesn’t think but acts, and he feels how things must go more than he can explain it. Even though neither you nor I, in talking together, would come to any definite plans, etc., perhaps we might mutually strengthen that feeling that something is ripening within us. And that is what I should like.

“Difficulties give us the opportunity to prove our greatness by overcoming them.”
Message dictated to Sanjeeva Reddy at Guruprasad (6 June 1960), as quoted in The God-Man : The Life, Journeys and Work of Meher Baba with an Interpretation of His Silence and Spiritual Teaching (1964) by Charles Benjamin Purdom, p. 353 <!-- also quoted in The Silent Master : Meher Baba, Avatar of the Age (1987), by Irwin Luck, p. 15 -->
General sources
Context: It is better to deny God, than to defy God.
Sometimes our weakness is considered strength, and we take delight in borrowed greatness.
To profess to be a lover of God and then to be dishonest to God, to the world and to himself, is unparalleled hypocrisy. Difficulties give us the opportunity to prove our greatness by overcoming them.

“In the middle of difficulty lies opportunity”

In recent years this has often been misquoted as: "Patience and perseverance have a magical effect before which difficulties disappear and obstacles vanish".
Oration at Plymouth (1802)
Context: Courage and perseverance have a magical talisman, before which difficulties disappear and obstacles vanish into air. These qualities have ever been displayed in their mightiest perfection, as attendants in the retinue of strong passions.

2004, Democratic National Convention speech (July 2004)
Context: In the end, that's what this election is about. Do we participate in a politics of cynicism or a politics of hope? I'm not talking about blind optimism here... No, I'm talking about something more substantial. It's the hope of slaves sitting around a fire singing freedom songs; the hope of immigrants setting out for distant shores; the hope of a young naval lieutenant bravely patrolling the Mekong Delta; the hope of a millworker's son who dares to defy the odds; the hope of a skinny kid with a funny name who believes that America has a place for him, too. Hope in the face of difficulty, hope in the face of uncertainty, the audacity of hope: In the end, that is God's greatest gift to us, the bedrock of this nation, a belief in things not seen, a belief that there are better days ahead.

Rien ne saurait étonner un Américain. On a souvent répété que le mot "impossible" n’était pas français; on s’est évidemment trompé de dictionnaire. En Amérique, tout est facile, tout est simple, et quant aux difficultés mécaniques, elles sont mortes avant d’être nées. Entre le projet Barbicane et sa réalisation, pas un véritable Yankee ne se fût permis d’entrevoir l’apparence d’une difficulté. Chose dite, chose faite.
