“A great man is always willing to be little.”
1840s, Essays: First Series (1841), Compensation
Context: Our strength grows out of our weakness. The indignation which arms itself with secret forces does not awaken until we are pricked and stung and sorely assailed. A great man is always willing to be little. Whilst he sits on the cushion of advantages, he goes to sleep. When he is pushed, tormented, defeated, he has a chance to learn something; he has been put on his wits, on his manhood; he has gained facts; learns his ignorance; is cured of the insanity of conceit; has got moderation and real skill. The wise man throws himself on the side of his assailants. It is more his interest than it is theirs to find his weak point. The wound cicatrizes and falls off from him like a dead skin, and when they would triumph, lo! he has passed on invulnerable. Blame is safer than praise. I hate to be defended in a newspaper. As long as all that is said is said against me, I feel a certain assurance of success. But as soon as honeyed words of praise are spoken for me, I feel as one that lies unprotected before his enemies. In general, every evil to which we do not succumb is a benefactor.

Positive Thinking Every Day : An Inspiration for Each Day of the Year (1993), "April 13"
Earlier variant: People become really quite remarkable when they start thinking that they can do things.

As quoted in The Life and Work of Martha Graham (1991) by Agnes de Mille, p. 264, <!-- de Mille precedes the Graham quotation with: "The greatest thing she ever said to me was in 1943 after the opening of Oklahoma!, when I suddenly had unexpected, flamboyant success for a work I thought was only fairly good, after years of neglect for work I thought was fine. I was bewildered and worried that my entire scale of values was untrustworthy. I talked to Martha. I remember the conversation well. It was in a Schrafft's restaurant over a soda. I confessed that I had a burning desire to be excellent, but no faith that I could be. Martha said to me, very quietly, ... " -->
Context: There is a vitality, a life force, an energy, a quickening that is translated through you into action, and because there is only one of you in all of time, this expression is unique. And if you block it, it will never exist through any other medium and it will be lost. The world will not have it. It is not your business to determine how good it is nor how valuable nor how it compares with other expressions. It is your business to keep it yours clearly and directly, to keep the channel open. You do not even have to believe in yourself or your work. You have to keep yourself open and aware to the urges that motivate you. Keep the channel open.... No artist is pleased. [There is] no satisfaction whatever at any time. There is only a queer divine dissatisfaction, a blessed unrest that keeps us marching and makes us more alive than the others.

“You may have to fight a battle more than once to win it.”
This quote is widely attributed to Margaret Thatcher on various websites, and also appears in a number of books, including The Concise Columbia Dictionary of Quotations, Columbia University Press (1989), ed. Robert Andrews, p. 320 : ISBN 0231069901. 9780231069908 , but without any further source information such as date, location or any other context.
One valid Thatcher quote which may be the basis for the version above appears in the Second Carlton Lecture http://www.margaretthatcher.org/document/105799 (‘Why Democracy Will Last’), delivered at the Carlton Club, London (November 26, 1984) : Mr. Chairman, each generation has to stand up for democracy. It can’t take anything for granted and may have to fight fundamental battles anew. You know that marvellous quotation from Goethe : ‘That which thy fathers bequeathed thee / Earn it anew if thou would possess it.’
Thatcher also expressed this thought in a Speech to Atlantic Bridge (May 14, 2003) http://www.margaretthatcher.org/document/111266, delivered at the St. Regis Hotel, New York City : My friends, every generation has to fight anew the battle for liberty.
