“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.

“Live as if you were to die tomorrow. Learn as if you were to live forever.”
Variant on aphorism "Study as if you were to live forever. Live as if you were to die tomorrow" pre-dating Gandhi, variously attributed to Isidore of Seville (c. 560 – 636), in FPA Book of Quotations (1952) by Franklin Pierce Adams, to Edmund Rich (1175–1240) in American Journal of Education (1877), or to Alain de Lille in Samuel Smiles's Duty https://books.google.com/books?id=33UzAAAAMAAJ&pg=PA363&dq=live+die+tomorrow+learn+forever&hl=en&sa=X&ved=0ahUKEwjd3s_2m57MAhWFMGMKHe-sAl8Q6AEIHDAA#v=onepage&q=live%20die%20tomorrow%20learn%20forever&f=false (1881).
The 1995 book "The good boatman: a portrait of Gandhi," states that Gandhi subscribed "to the view that a man should live thinking he might die tomorrow but learn as if he would live forever."
In his 2010 Boyer lecture Glyn Davis (Professor of Political Science and Vice-Chancellor of Melbourne University) attributes the quote to Desiderius Erasmus. "He [Erasmus] reworked Pliny to urge 'live as if you are to die tomorrow, study as if you were to live forever'. Many students obey the first clause - the best heed both."
There is a similar quote by Johann Gottfried Herder: "Mensch, genieße dein Leben, als müssest morgen du weggehn; Schone dein Leben, als ob ewig du weiletest hier." ["Man, enjoy your life as if you were to depart tomorrow; spare your life as if you were to linger here forever."] (Zerstreute Blätter, 1785).
