Workshops and retreats can be immensely helpful in any number of ways to writers, artists and craftspersons alike. If someone feels blocked…well, where there is a will there is always a way. Good research is helpful. Or, just tell the story, paint the picture and do more research later. There is always room for improvement, yes it is a lifelong journey! Look at Monet. He painted the same scene many times over in every kind of light, and learned.
