This line from Frost is often lifted out as a slogan, but in the poem it comes from a tired person describing a life that feels overburdened. That context matters. Going “through” is not always heroic or clean. Sometimes it means admitting that there is no shortcut around what needs to be faced. The value of the line may be less about pushing harder and more about stopping the search for an imaginary escape route. What might change if you stopped looking for a way around it?
