How to help a 5 year old realise she wants/needs to read

We are having a problem encouraging my 5 year old granddaughter to practice her reading at home. Last night she said she doesn't need to read because she wants to be an artist not a librarian! She was progressing very well last year and because of this was advanced to a harder group. Now she refuses to read to Mum or me. Has anyone encountered this problem and have any suggestions as to how we can help her please?
