Things won are done; joy's soul lies in the doing.

Our reading
An editorial interpretation.
The line locates joy in doing rather than in having finished. Completed achievements belong to what is already over, while activity holds the pleasure. One reading treats the process itself as valuable, giving effort and pursuit a life that settled accomplishments lack.
