How To Have A Scottish Accent

I have been using this video as a way of helping me Try and do a scottish accent. At the moment I am finding it very difficult. However this video has helped me with certain points such a rolling R's. I feel that if I keep practicing the accent it will come over time. However learning the accent is not my goal as of yet. At the moment i am focusing on developing my character and learning my lines first. When i know my lines the accent will be easier to do and i can focus all my time on learning how to do it instead of trying to multitask.
