Legacies are what we'll be remembered for. Horatius Bonar had this to write:

Fading away like the stars of the morning,
Losing their light in the glorious sun--
Thus would we pass from the earth and its toiling,
Only remembered by what we have done.

Refrain:

Only remembered, only remembered,
Only remembered by what we have done;
Thus would we pass from the earth and its toiling,
Only remembered by what we have done.
