A little more persistence, a little more effort, and what seemed hopeless failure may turn to glorious success. There is no failure except in no longer trying. There is no defeat except from within, no really insurmountable barrier save our own inherent weakness of purpose.

As quoted from Electrical Review (c. 1895) without further attribution in The Search for the North Pole (1896) by Evelyn Briggs Baldwin, p. 520, this was later published as part of various works by Hubbard, including FRA Magazine : A Journal of Affirmation (1915), and An American Bible (1918) edited by Alice Hubbard. A portion of this was once misattributed to Amelia J Calver in The Manifesto (January 1896) by the United Society of Believers in Christ’s Second Appearing (Shakers), p. 184, and more recently to Kin Hubbard at some sites on the internet.
