I shall not pass this way again - Grellet:

I expect to pass through this world but once;

any good thing therefore that I can do, or any

kindness that I can show to any fellow-creature,

let me do it now; let me not defer or neglect it,

for I shall not pass this way again.

(Seems it has changed slightly over the years, but I think has same meaning really, even though some text missing...)
