Ernesto Che Guevara said this quote

Individuals start to see themselves reflected in their work and to understand their full status as human beings through the object created, through the work accomplished. Work no longer entails surrendering a part of one's being in the form of labor power sold, which no longer belongs to the individual, but becomes an expression of oneself, a contribution to the common life in which one is reflected, the fulfillment of one's social duty.
