“Fain would I climb, yet fear I to fall.”
Poem written in a glass window obvious to the Queen's eye, reported in Bartlett's Familiar Quotations, 10th ed. (1919). "Her Majesty, either espying or being shown it, did under-write, 'If thy heart fails thee, climb not at all'", Thomas Fuller, Worthies of England, vol. i. p. 419.
