“In shooting it’s very similar, you look at the grand scheme of things and then you break it all down and then ideally parcel out individual pieces and become proficient until you have all that end-result that all fits together.”

“Neither of us knew about this business, but the possibility of investing came up and we opened the shop. I could dye someone, but it would take a long time. When I’m there I help to pick up the phone for appointments, help with the customers or I am at the till”, she told Mundo Deportivo.
