Dhamma Verses (Dhammapada, KN 2)

8: The Chapter about the Thousands – 113
One day of striving is better
Ven. Sappadāsa was dissatisfied and thought to end his life,
but became an Arahat with the razor at his windpipe; when
questioned by the monks the Buddha explained that one who
truly strives can attain Awakening in an instant, and he spoke
this verse.
112. Yo ca vassasataṁ jīve, kusīto hīnavīriyo,
ekāhaṁ jīvitaṁ seyyo, vir i yam-ārabhato daḷhaṁ.
One might live for a hundred years,
indolent, with less energy,
but one day is better, for one
with energy set up and firm.
