Noun
One who toils, or labors painfully.
Source: Webster's dictionaryNot to the curious or impatient soulThat in the start, demands the end be shown,And at each step, stops waiting for a sign;But to the tireless toiler toward the goal,Shall the great miracles of God be knownAnd life revealed, immortal and divine. Ella Wheeler Wilcox
It is easy to tell the toiler How best he can carry his pack But no one can rate a burden's weight Until it has been on his back. Ella Wheeler Wilcox
