Dirt Off Ya Shoulder 

To step up. The origin of this term comes from a story in which a donkey falls into a well and cannot get out. The farmer tries to get the donkey out by rope, unsuccessful in his attempt. He decides, instead, to just give up and bury the donkey in the well. As the farmer begins filling the hole with dirt, the donkey becomes depressed, realizing that all of the dirt on his shoulders and back were going to eventually bury him. He then thought of an idea: I can just shake it off and step up. Therefore, he could just die by doing nothing and getting buried, or shake the dirt off his shoulders and step up to the occasion.

Dont let it get your down hommie , brush that dirt off ya shoulder.
