What us the theme if the poem dust of snow?

The theme of this poem is very significant because it tells us how to take the opporunities that come our way without wasting our timebrooding over the past. Sometimes we face failuebut if we brood over it and become upset, then we waste our valuable time that could be used in good work. The poet had been siiting under a hemlock tree wasting a lovely day because he was upset about something, but when a crow shook some dust of snow on him , he felt happy and looked at things in a new light
