They Call Me Coach (1972)
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).

“Act as if you were to die tomorrow, but to die in order to survive and be eternalized.”
The Tragic Sense of Life (1913), XI : The Practical Problem
Context: And what is its moral proof? We may formulate it thus: Act so that in your own judgment and in the judgment of others you may merit eternity, act so that you may become irreplaceable, act so that you may not merit death. Or perhaps thus: Act as if you were to die tomorrow, but to die in order to survive and be eternalized. The end of morality is to give personal, human finality to the Universe; to discover the finality that belongs to it — if indeed it has any finality — and to discover it by acting.

“You have no birthday because you have always lived; you were never born, and never will die.”
There's No Such Place As Far Away (1978)
Context: You have no birthday because you have always lived; you were never born, and never will die. You are not the child of the people you call mother and father, but their fellow-adventurer on a bright journey to understand the things that are.
